ECG من البداية للاحتراف

ECG من البداية للاحتراف هو كتاب ممتاز فى شرح رسم القلب 
The electrocardiogram (ECG or EKG) is a special graph that represents the electrical activity of the heart from one instant to the next. Thus, the ECG provides a time-voltage chart of the heartbeat. For many patients, this test is a key component of clinical diagnosis and management in both inpatient and outpatient settings. The device used to obtain and display the conventional ECG is called the electrocardiograph, or ECG machine. It records cardiac electrical currents (voltages or potentials) by means of conductive electrodes selectively positioned on the surface of the body. 

This book is devoted to explaining the basis of the normal ECG and then examining the major conditions that cause abnormal depolarization (P and QRS) and repolarization (ST-T and U) patterns.  
Why is the ECG so clinically useful ? The ECG is one of the most versatile and inexpensive of clinical tests. Its utility derives from careful clinical and experimental studies over more than a century showing the following:  It is the essential initial clinical test for diagnosing dangerous cardiac electrical disturbances related to conduction abnormalities in the AV junction and bundle branch system and to brady- and tachyarrhythmias.  It often provides immediately available information about clinically important mechanical and metabolic problems, not just about primary abnormalities of electrical function. Examples include myocardial ischemia/infarction, electrolyte disorders, and drug toxicity, as well as hypertrophy and other types of chamber overload.  It may provide clues that allow you to forecast preventable catastrophies. A good example is a very long QT(U) pattern preceding sudden cardiac arrest due to torsades de pointes.
