The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
Myocardial infarction complications may occur immediately following a myocardial infarction (heart attack) (in the acute phase), or may need time to develop (a chronic problem). After an infarction, an obvious complication is a second infarction, which may occur in the domain of another atherosclerotic coronary artery, or in the same zone if ...
It can be seen in approximately 4% of cases of acute myocardial infarction [citation needed] It is the most common type of intraventricular conduction defect seen in acute anterior myocardial infarction, and the left anterior descending artery is usually the culprit vessel. It can be seen with acute inferior wall myocardial infarction.
This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25] Coronary ischemia resulting from coronary artery disease also increases the risk of developing heart failure. [10] Most cases of heart failure result from underlying coronary artery disease.

Ventricular aneurysms are one of the many complications that may occur after a heart attack.The word aneurysm refers to a bulge or 'pocketing' of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum, or within the aorta.
Common causes include normal variation, changes in bundle branch structure - such as mechanical stretching, chest trauma, right ventricular hypertrophy or strain, congenital heart disease such as atrial septal defect, and ischemic heart disease.
A myocardial infarction in the setting of a paradoxical embolism are caused by the emboli disrupting blood flow in a coronary artery. Physical findings that should be evaluated include a comprehensive neurological examination for evaluation of stroke symptoms such as weakness, gait changes, slurred speech, and facial droop.
Atrial septal defect with left-to-right shunt. The left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. There are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. [1]
