Free down load, ECG Book “ECG in clinical practice”.

E
CG in clinical practice Version 1  is meant for doctors who are a novice or know very little about ECG. In the daily practice of medicine, it is impossible for any speciality doctor, not to come across cardiac related problems with a need of ECG.

Patient relatives and Doctors

W
e Doctors are taught how to treat patients, we even understand patient feelings to certain extent but we are not attentive towards patient relatives. This is major reason for most hospital violence. In India,  decision of treatment, is taken by patient relatives unlike in the west,

CHAPTER 10. CHAMBER ENLARGEMENT

F
our chambers of heart enlarge either due to volume over load or pressure overload. Volume overload is caused by dilated cardiomyopathy, aortic regurgitation, mitral regurgitation and etc. Volume overload is also called as diastolic or eccentric hypertrophy. Pressure overload is caused by lesions like aortic stenosis, pulmonary stenosis, hypertrophic cardiomyopathy and etc. Pressure overload is also called as systolic or concentric hypertrophy. ECG is not much useful in differentiating volume and pressure overload.

CHAPTER 9. VENTRICULAR CONDUCTION ABNORMALITIES

C
onduction of electrical impulse across ventricles is by two main bundles i.e. left and right bundles; these conduct impulse to left and right ventricles respectively. Left bundle further subdivides into anterior or superior and posterior or inferior fascicles. We will use anterior and posterior terms hence forth.

CHAPTER 8. AXIS AND HEXAGONAL DIAGRAM.

A
xis calculation of waves and segments of ECG is important in diagnosing cardiac diseases. Diseases like Hypertrophy, enlargement, dextrocardia and conduction abnormalities have effect on axis. Vertical plane axis is used most commonly and it is described in this chapter. Hexagonal diagram becomes important utility in calculating vertical plane axis.

CHAPTER 7. ECG IN EXTRA CARDIAC DISEASE

S
ome non cardiac diseases have effect on ECG. Namely , Intra cranial pathology, electrolytes imbalances like hypokalemia, hyperkalemia, hypocalcemia, hypercalcemia and endocrine diseases like  hypothyroidisium and hypothermia. These ECG changes,  sometimes help clinician, and during other times  may confuse diagnosis of cardiac disease itself. Even some drugs also have affect on ECG.

CHAPTER 6. ISCHEMIC HEART DISEASE.

T
hese are group of diseases, which are result of reduced blood supply to wall of heart. Heart has its own arteries called as coronary arteries, namely, left coronary artery and right coronary artery. Both arteries originate from aorta, i.e. left coronary and right coronary sinus of aorta respectively. Left coronary artery (left main artery) further divides into Left anterior descending and left circumflex artery. See Figure 19.
