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

ECG Tip: LBBB vs. RBBB Made Easy! 🫀 👉 But what are these blocks? A bundle branch block happens when the electrical signals traveling through the heart’s bundle branches (which control the ventricles) are slowed or blocked. This delay can affect how the ventricles contract, leading to the characteristic wide QRS complexes seen on an ECG. Causes can include structural heart changes, ischemia, hypertension, or scarring from prior heart conditions. 👉 Want to learn more? Watch our latest YouTube v
