Health Technology

The principle behind how the Kealthtech smartwatch monitors ECG (Electrocardiogram) involves several key steps and technologies:

Electrode Sensors: The Kealthtech smartwatch is equipped with two or more electrodes that come into contact with the skin. One electrode is typically located on the back of the watch, touching the wrist, while another is placed on the watch's edge, which the user needs to touch with the other hand.

Electrical Signal Acquisition: When the user touches the electrodes, the sensors detect the weak electrical signals generated by the heart with each beat. These signals reflect the electrical activity of the heart.

Signal Amplification and Filtering: Because the heart's electrical signals are very weak, the smartwatch's internal amplifiers enhance these signals. Simultaneously, the watch filters out other interfering signals, such as muscle movement or environmental noise, to obtain a clearer ECG signal.

Analog-to-Digital Conversion: The amplified and filtered analog electrical signals are converted into digital signals using an analog-to-digital converter (ADC), allowing for subsequent processing and analysis.

Data Processing and Analysis: The digitized ECG signals are analyzed by the watch's processor. Algorithms analyze these signals to identify various heart activities, such as heart rate, rhythm, and potential abnormalities (e.g., atrial fibrillation).

Data Display and Storage: The processed data is displayed on the watch's screen, typically in the form of a graph showing the ECG. The data can also be synced to a smartphone app or cloud service for further review and analysis by the user or a healthcare professional.

The core of ECG monitoring in the Kealthtech smartwatch involves detecting the heart's electrical activity through electrodes, processing and analyzing the signals, and providing real-time heart health data to the user. This technology helps users monitor their heart health and detect potential issues early.

HRV stands for Heart Rate Variability. It is a measure of the variation in time between each heartbeat. This variation is controlled by the autonomic nervous system, specifically the balance between the sympathetic and parasympathetic branches.

Uses of HRV
Stress Monitoring: HRV is often used to assess stress levels. Lower HRV typically indicates higher stress and less resilience, while higher HRV indicates better stress management and overall autonomic nervous system health.

Fitness and Training: Athletes use HRV to monitor their recovery and training status. High HRV suggests that an individual is well-recovered and ready for intensive training, whereas low HRV may indicate fatigue or overtraining.

Health Monitoring: HRV can be a marker for overall cardiovascular health. Abnormal HRV readings can indicate potential heart problems, including arrhythmias and other heart conditions.

Sleep Quality: HRV is used to assess sleep quality and recovery. Good sleep is associated with higher HRV, reflecting a well-functioning autonomic nervous system.

Mental Health: HRV is used in psychological research and therapy to understand and treat conditions like anxiety and depression. It provides insights into how the body is responding to mental stress.

Chronic Disease Management: HRV monitoring can help manage chronic conditions such as diabetes and hypertension by providing feedback on how well these conditions are being controlled.

In summary, HRV is a valuable metric for assessing physical and mental well-being, providing insights into stress, recovery, fitness, and overall health.

Enable Scientific Sleep Monitoring: In the settings of your Kealthtech smartwatch, enable the "Scientific Sleep" or "All-day Sleep Monitoring" feature.

Wear the Watch During Sleep: Wear the smartwatch during your sleep, typically between 12:00 AM and 7:00 AM.

Check the Results in the App: The next day, open the corresponding app, "H-band," on your smartphone to view the monitoring results.

Lorenz Scatter Plot Display: The HRV results will be displayed in the form of a Lorenz scatter plot.

Compare and Analyze: Compare your plot with the sample plots provided in the app to understand your HRV analysis and results.

By following these steps, you can effectively monitor your HRV using the Kealthtech smartwatch and analyze your health with the detailed insights provided in the app.

Health Awareness: Smartwatch heart rate monitoring provides users with real-time insights into their cardiovascular health, allowing them to track their heart rate patterns over time and identify any irregularities or fluctuations.

Fitness Tracking: Monitoring heart rate during exercise sessions helps users optimize their workouts by ensuring they stay within their target heart rate zones for maximum effectiveness and safety.

Stress Management: Changes in heart rate can indicate stress levels. By monitoring heart rate throughout the day, users can identify periods of heightened stress and take proactive measures to manage stress levels effectively.

Early Detection of Health Issues: Abnormal heart rate patterns detected by smartwatches can serve as early indicators of potential health issues, such as arrhythmias or atrial fibrillation. Timely detection allows users to seek medical attention and intervention promptly.

Overall Well-being: Consistent heart rate monitoring promotes a proactive approach to health and well-being, empowering users to make informed lifestyle choices and prioritize activities that contribute to heart health and overall wellness.

Heart rate distribution refers to the variation of heart rate over a period of time, typically presented in statistical form. This distribution can display the average level of heart rate, as well as the highest and lowest values, and the distribution of heart rate within different ranges.

Heart rate distribution can provide important information about heart health and overall physical condition. For instance, under normal circumstances, a person's heart rate should fluctuate within a certain range, being lower during rest and higher during exercise or stress. By observing heart rate distribution, one can understand how an individual's heart rate responds in different situations, thereby assessing their cardiac health.

In the fields of medicine and sports science, heart rate distribution is also commonly used to evaluate training effectiveness and physiological adaptation. The heart rate distribution of athletes or fitness enthusiasts can reflect their training status and cardiac adaptability, aiding in the adjustment of training plans and improvement of athletic performance.

Kealthtech smartwatches use advanced heart rate sensor technology to provide comprehensive health insights through continuous monitoring. The optical sensor, usually positioned on the device's underside, employs photoplethysmography (PPG) to measure heart rate.

During monitoring, the sensor emits a green light that penetrates the skin and interacts with the red blood cells circulating in the blood vessels. As the heart pumps blood throughout the body, the volume of blood in the vessels fluctuates, causing variations in the amount of light absorbed and reflected by the blood cells. These fluctuations are captured by the sensor and translated into heart rate measurements in beats per minute (BPM).

In addition to optical sensors, some Kealthtech smartwatches offer the option to pair with compatible heart rate straps for enhanced accuracy during specific activities like running, cycling, or cardio training. These straps detect the electrical signals generated by the heart's contractions. While effective for intense physical activities, wearing a chest strap continuously may be inconvenient for all-day monitoring.

The KealthTech watch features an abnormal heart rate alert function. When the watch detects a heart rate that is excessively high and may potentially impact your health, it will vibrate to alert you. If your watch is connected to the mobile app, you can access this feature by tapping on the heart rate module within the app. At the bottom of the module page, you can choose to enable or disable the alert. By tapping the ">" symbol next to "Enable Alert," you can set the upper limit for your resting heart rate.

The Kealthtech smart watch monitors sleep using a combination of sensors and algorithms. Here's how it works:

Sensors: The watch is equipped with various sensors, including an accelerometer and a heart rate monitor. The accelerometer tracks your movements while you sleep, and the heart rate monitor measures your heart rate variability.

Data Collection: As you sleep, the watch collects data on your movement and heart rate. It records when you are still and when you move, as well as changes in your heart rate.

Sleep Stages: The watch uses algorithms to analyze the collected data and determine different sleep stages. These typically include light sleep, deep sleep, and REM sleep. The algorithms interpret patterns in your movement and heart rate to categorize these stages.

Sleep Analysis: After you wake up, the watch processes the data and provides a detailed sleep report. This report usually includes the total duration of your sleep, the time spent in each sleep stage, and insights into your sleep quality.

Feedback and Recommendations: Based on the sleep analysis, the smart watch may offer personalized recommendations to improve your sleep, such as maintaining a consistent sleep schedule or adjusting your bedtime routine.

By continuously monitoring and analyzing your sleep patterns, the Kealthtech smart watch helps you understand and improve your sleep quality.
