To use a portable EKG device, place the electrodes on clean skin as directed, stay still during the recording, and follow your device’s specific instructions for starting the measurement. Most…

Home cardiac monitoring refers to the use of portable devices that track your heart’s electrical activity, rhythm, and rate from the comfort of your own home. These FDA-approved devices allow…

An echocardiogram uses ultrasound waves to create moving images of your heart, while an ECG records the electrical activity of your heartbeat on paper or a screen. The main difference…

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…
