ECG interpretationrequires firm knowledge of the characteristics of the normal ECG. The waves, intervals, durations and assessment of rhythm is fundamental to ECG interpretation. Below follows a brief summary of the ECG waves, their appearance, terminology, physiological background and interpretation. See more Figure 1. The classical ECG curve with its most common waveforms. Important intervals and points of measurement are depicted. ECG interpretation requires knowledge of these waves and intervals. See more ECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the … See more The QRS complex reflects the depolarization (activation, contraction) of the ventricles. Although it may not always include a Q-wave, R-wave and S-wave, it is still referred to as a QRS complex. In other words, if … See more WebApr 2, 2024 · An ECG is used to detect abnormalities in the heart by assessing different waves in the rhythm.

Introduction to ECG Learn the Heart - Healio
WebAn EKG measures electrical activity of the heartbeat, which is your body’s way of moving blood. Heartbeats are created by an electrical impulse that causes the heart to contract, or squeeze. This pushes blood through the … WebAug 23, 2024 · In a normal ECG, there's three distinct waves. Together these waves represent one heartbeat. Looked at separately, the waves tell us what's happening in the heart at a certain time. The... WebThis picture shows an ECG (electrocardiogram, EKG) of a person with an abnormal rhythm (arrhythmia) called an atrioventricular (AV) block. P waves show that the top of the heart received electrical activity. Each P wave is usually followed by the tall (QRS) waves. QRS waves reflect the electrical activity that causes the heart to contract. download apk filmora tanpa watermark
