Explore the subtle yet critical electrocardiogram (ECG) features of Brugada Syndrome Type 2, a complex channelopathy with a risk of sudden cardiac death. This article delves into the characteristic "saddle-back" ST elevation, its differentiation from other conditions, and the diagnostic role of sodium channel blocking drugs.

Explore the distinctive electrocardiogram (ECG) features of Wolff-Parkinson-White (WPW) Syndrome, a pre-excitation disorder with significant clinical implications. This article provides a detailed explanation of the characteristic delta wave, short PR interval, and wide QRS complex, crucial for accurate diagnosis and management.

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.

The heart’s ability to beat rhythmically depends on its specialized conduction system, a network that coordinates electrical impulses for efficient pumping. This anterior view of a frontal section diagram illustrates key components such as the sinoatrial node, internodal pathways, atrioventricular node, atrioventricular bundle, right bundle branch, left bundle branch, and Purkinje fibers, offering a clear view of how these structures regulate cardiac activity. Exploring this image provides a deeper understanding of the electrical framework that sustains circulation.
