EKG artifacts are unwanted signals on your electrocardiogram that can make your heart rhythm look abnormal when it’s actually normal. These false readings come from muscle movement, loose electrodes, electrical…

A normal ST segment appears as a flat, horizontal line on an ECG that connects the QRS complex to the T wave, sitting at the same level as the baseline…

To measure the RR interval on an EKG strip, find two consecutive R waves and count the number of large squares between their peaks, then multiply by 0.20 seconds per…

The J-point on your EKG reading is the spot where the QRS complex ends and the ST segment begins, appearing as a small junction between these two important parts of…

Home EKG devices can detect some heart rhythm problems, but they’re not good enough for complete medical diagnosis and shouldn’t replace professional evaluation. Your doctor needs more detailed testing and…

ST depression on home EKG appears as a downward dip in the ST segment, which may signal heart problems like coronary artery disease or medication effects. You should contact your…

Common EKG findings for atrial fibrillation include an irregularly irregular heart rhythm and the absence of clear P waves on the electrocardiogram strip. You can spot atrial fibrillation on an…

A bundle branch block on your EKG appears as a widened QRS complex (wider than 120 milliseconds) with specific wave patterns that show delayed electrical conduction through your heart’s ventricles….

An inverted T wave on an EKG happens when the T wave points downward instead of upward, often indicating heart muscle problems or blood flow issues. This pattern can signal…

Normal P wave amplitude ranges from 0.5 to 2.5 millimeters (0.05 to 0.25 millivolts) in standard EKG leads, with the tallest waves typically seen in leads II and V1. A…
