Common ECG Abnormalities Diagram: A Detailed Guide

An electrocardiogram (ECG) is a critical tool for identifying heart irregularities, revealing abnormalities that can indicate underlying cardiac conditions. This diagram illustrates common ECG abnormalities, including second-degree block, atrial fibrillation, ventricular tachycardia, ventricular fibrillation, and third-degree block, each with distinct patterns that correlate to specific electrical and mechanical dysfunctions. Exploring this image provides valuable insights into recognizing and understanding these cardiac irregularities.

Action Potential at the SA Node Diagram: A Comprehensive Overview

The sinoatrial (SA) node, as the heart’s natural pacemaker, generates electrical impulses that initiate each heartbeat, a process vividly illustrated in this diagram. This image details the prepotential, threshold, rapid depolarization, and repolarization phases, highlighting the unique absence of a resting potential and the role of sodium ion influx in driving spontaneous activity. Exploring this diagram provides a clear understanding of how the SA node sustains the heart’s rhythmic contractions.
