Heart rate monitoring only tells you how fast your heart beats, while ECG shows the electrical activity that makes your heart beat properly. Your pulse can be normal even when…

T wave abnormality appears when the electrical recovery phase of your heartbeat shows unusual patterns on an ECG, often indicating heart muscle stress or damage. These changes can signal anything…

The QRS complex on your EKG shows how electricity moves through your heart’s main pumping chambers, with each wave representing a different part of this electrical journey. A normal QRS…

The P wave is the first wave on your EKG strip that shows your heart’s upper chambers (atria) contracting to push blood into the lower chambers. Understanding the P wave…

Heart electrical signals are the electrical impulses that coordinate your heartbeat, traveling through specialized pathways in your heart muscle to create the rhythmic contractions you feel as your pulse. Your…

Smartwatch ECG features can detect some heart rhythm problems, but they’re not as accurate as medical EKG machines used by doctors. Your smartwatch ECG works well for basic heart monitoring,…

A 12-lead ECG is a heart test that uses 12 different electrical views to check your heart’s rhythm, detect problems, and diagnose conditions like heart attacks or arrhythmias. This test…

Normal sinus rhythm is when your heart beats in a regular pattern between 60-100 beats per minute, starting from the sinoatrial (SA) node. This natural heartbeat pattern shows your heart’s…

An ECG (electrocardiogram) measures your heart’s electrical activity to detect heart problems, rhythm issues, and other cardiovascular conditions that might not show symptoms. Your doctor uses ECG results to diagnose…

Heart event monitors are portable devices that record your heart’s electrical activity when you experience symptoms like chest pain, palpitations, or dizziness. These monitors work by detecting irregular heart rhythms…
