divided by a partition or septum into two halves‚ and the halves are in turn divided into four chambers. The heart is situated within the chest cavity and surrounded by a fluid filled sac called the pericardium. This amazing muscle produces electrical impulses that cause the heart to contract‚ pumping blood throughout the body. The heart and the circulatory system together form the cardiovascular system. Heart Anatomy: Chambers Atria - upper two chambers of the heart. Ventricles - lower two

cardiac arrhythmia‚ ventricular fibrillation and pulseless ventricular tachycardia. The procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and re-establishes normal conduction of the heart’s electrical impulse. The machine used to deliver this therapeutic shock to the heart is called a defibrillator. Defibrillators are key devices in maintaining

Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic____ __cardiac__ cells that initiate and distribute __impulses_____ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of ____heart depolarization____. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA node _sets the pace for the

EKG Rhythm Interpretation How to Analyze a Rhythm All MIHS hospital nursing staff must complete an EKG test with a score of at least 80% upon hire. All hospital RNs are tested annually. This includes recognizing the rhythms‚ measuring the intervals‚ and knowing the appropriate treatment/algorithm according to American Heart Association. This is basic ACLS/PALS information‚ nothing new. In addition to this study packet‚ there are multiple websites that can be accessed on the

The heart beats to fast‚ heart rate increases. The heart beats sluggishly‚ heart rate decreases. However‚ in the process of how the heart beats‚ more specific problem is differentially diagnosed. To be able to view the actual electrical conduction and heart contraction process that may lead us to the specific problem of the patient‚ a machine that reflect the electrical functioning of the heart is needed. That is why the electrocardiogram or ECG (others‚ EKG) existed. An Electrocardiograph
