Electrocardiogram

The book introduces ECG as a method to visualize the electrical activity of the heart and explains its role in detecting arrhythmias, conduction problems, and heart attacks. Key concepts such as the function of sodium and potassium in cardiac conduction, the meaning of bradycardia and tachycardia, and the importance of P-waves and QRS complexes are covered.

Different cardiac rhythms and disorders are outlined, including sinus rhythm, junctional rhythm, ventricular tachycardia, ventricular fibrillation, atrial fibrillation, and atrial flutter. Heart blocks are described in detail, including first-degree, second-degree type 1 (Wenckebach), second-degree type 2 (Mobitz 2), and third-degree blocks.

The book also explains how to interpret ECG strips, the role of small and large tiles in time measurement, and the identification of conditions such as STEMI, NSTEMI, and Wolff Parkinson White Syndrome.

An informative reference for students, healthcare workers, and general audiences who want to understand electrocardiograms, their interpretation, and their importance in detecting heart disease.
