The heart’s electrical system consists of specialized cells that create and conduct electrical impulses to coordinate your heartbeat through the sinoatrial node, atrioventricular node, and Purkinje fibers. Your heart beats…
Wearable heart sensors use photoplethysmography (PPG) technology and electrical conductivity to measure your heart’s activity through your skin in real-time. These tiny devices combine LED lights, photodetectors, and electrodes to…
An EKG cannot directly detect a stroke, but it can reveal heart rhythm problems that increase your stroke risk by up to 5 times. While EKGs detect electrical heart activity,…
Yes, an ECG can detect signs of a silent heart attack, but only if it’s taken during or shortly after the event when electrical changes are still visible. Silent heart…
HRV and ECG work together by showing different aspects of your heart’s function – ECG records electrical activity while HRV measures beat-to-beat timing variations from that same data. Your heart…
Heart Rate Variability (HRV) is the tiny time differences between your heartbeats, measured in milliseconds, which shows how well your nervous system responds to stress and recovery. Higher HRV typically…
Heart palpitations are irregular, rapid, or forceful heartbeats that you can feel in your chest, neck, or throat, and ECG tracking provides real-time monitoring to help identify their patterns and…
An inverted T wave on your ECG may signal heart problems, but it’s not always dangerous and can appear in healthy people too. Your doctor needs to review your complete…
Bundle branch block occurs when electrical signals in your heart get delayed or blocked as they travel through the left or right bundle branches of your heart’s conduction system. EKG…
ST segment elevation on an ECG is a warning sign that shows your heart muscle isn’t getting enough blood, often during a heart attack. When you see ST segment elevation,…
