ECG interpretation involves systematically analyzing the waveforms and intervals to assess heart rhythm, rate, and overall electrical activity. This includes evaluating the P-wave (atrial depolarization), PR interval, QRS complex (ventricular depolarization), ST segment, T-wave (ventricular repolarization), and QT interval. A normal ECG typically shows a regular heart rate (60-100 bpm), normal P-waves, a PR interval between 120-200 ms, a QRS complex duration less than 120 ms, and a normal QT int

Let's get down to the beat in today's #ClinicalCuts: ECG basics! An electrocardiogram (ECG) is a tool used to visualize, or “gram,” the electricity, or “electro,” that flows through the heart, or “cardio.” Specifically, a 12-lead ECG tracing shows how the depolarization wave, which is a wave of positive charge, moves during each heartbeat by providing the perspectives of different sets of electrodes. This particular set of electrodes is called lead II; one electrode is placed on the right arm an
