ECG Test Explained What It Detects How to Read Your Report and When You Need One Have you ever wondered what those lines and waves on an ECG report actually mean An ECG Test is one of the most common

heartbeat begins with an electrical signal that travels through the heart muscle allowing it to pump blood throughout the body During the test small adhesive electrodes are placed on your chest arms and legs These electrodes record your heart activity and produce a graph that your cardiologist uses to evaluate your heart rhythm and detect abnormalities The test usually takes less than five minutes It does not require fasting injections or recovery time making it one of the safest and easiest heart tests available What Does an ECG Test Detect An ECG Test helps doctors identify a wide range of heart conditions including Heart attack Previous silent heart attack Irregular heartbeat Fast heart rate Slow heart rate Poor blood supply to the heart Heart enlargement Electrical conduction

normally Once the recording is complete the electrodes are removed and you can immediately continue your daily routine How to Read Your ECG Report Your ECG report contains several important measurements that help your cardiologist understand your heart health Heart Rate A normal resting heart rate is usually between sixty and one hundred beats per minute Heart Rhythm Normal Sinus Rhythm

provides only an automated interpretation The final diagnosis should always come from an experienced heart specialist Can You Have a Normal ECG and Still Have Heart Disease Yes A normal ECG does not
