CARDIO – 1/8/08. Cardiac Rate, Cardiac Rhythm, Axis Deviation, Blocks, and Ischemia – This material makes up 95% of all cardiac problems. We will not be looking at bacterial or viral infections of the heart. 12 Lead EKG. The standard EKG is 12 leads. A lead refers to a view of the heart. There are 12 views of the heart in a normal EKG.

A small area of the heart can become more excitable than normal, which causes abnormal heart beats called ectopy. Ectopic foci are usually caused by an irritable area in the heart. This irritability can be caused by ischemia, stimulants such as nicotine and caffeine, lack of sleep or anxiety (Guyton, 1982).

Myocardial ischemia induced by abnormal thick-wall intramural coronary arteries, trigger factor for fibrosis and compensatory hypertrophy. Several other mechanisms have been suggested as causes of myocardial ischemia in patients with HCM (table XIX-2), but the predominant mechanism, or a general ischemic pattern was still impossible to be ...

In the final analysis, the likelihood that a positive (abnormal) ECG exercise test represents ischemia will depend on the degree of suspicion before the test, the factors surrounding the test, all modified by the results of any additional studies done afterwards.

CHAPTER 15: THE CARDIOVASCULAR SYSTEM: BLOOD VESSELS & HEMODYNAMICS. I. INTRODUCTION. The blood vessels form a closed system of tubes that carry blood away from the heart, transport it to all the body tissues and then returns it to the heart. Hemodynamics is the study of the forces involved in accomplishing that feat. II. TYPES OF BLOOD VESSELS:

Note- one normal ECG does not exclude cardiac ischemia. Leads & relationship to heart Septum = V1-V2 Anterior wall = V3-V4 Lateral wall = V5, V6, I, aVL Inferior wall = II, III, aVF. 1. Look for . Q waves. Pathological Q waves indicates an AMI (new or old). Any Q wave in V1-V3 0.03 seconds or wider (0.03 seconds is ¾ width of one little square)

The electrocardiogram (ECG) is one of the most useful diagnostic tests in emergency medicine. It is an easy and inexpensive test that is used routinely in the assessment of patients with chest pain. The ECG is the cornerstone for making the diagnosis of cardiac ischemia and is used for making decisions about eligibility for thrombolytic therapy.
