INTRODUCTION
INTRODUCTION Cardiac Location and Structures The heart is the driving force of the circulatory system, contracting about 70 times/minute to pump an adequate volume of blood with sufficient pressure to perfuse all body organs and tissues. The muscular organ, about the size of a clenched fist, weights from 300 to 400 g. It is located within the mediastinum of the thoratic cavity, above the diaphragm and between the lungs. This location subjects the heart's activity to influence from all pressure ...

Cardiac Pacemakers
Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to...

Ventricular Tachycardia
Ventricular Tachycardia Meg Carroll June 28, 2000 Ventricular Tachycardia An dysrhythmia of the heart is an irregular heartbeat rhythm. Ventricular tachycardia is an dysrhythmia in which the lower chambers of the heart, the ventricles, beat unusually fast. The heart rate is measured with an electrocardiogram, or ECG. This is a machine that measures the electrical impulses from the patient's heart. This is displayed on a monitor or ECG graph paper. The boxes on the graph paper measure time. Five ...

Electrocardiogram
Electrocardiogram Electrocardiogram Lab Introduction Electrocardiograms are used to obtain information about the function of the heart. An ECG is a recording of the electrical activity of the heart made from electrodes placed on the surface of the skin. Salt solutions are good conductors of electricity and can transfer electrical activity to the skins surface. An ECG tracing shows the sum of the electrical potentials generated by all the cells of the heart at any moment (Silverthorn, 1998). Each...
