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

The pacemaker leads were advanced under fluoroscopic and electrophysiologic guidance into the right ventricular apex and right atrial appendage. The pacemaker leads were seen to function adequately in vivo and were sutured in place with 0 silk. The leads were connected to the pulse generator‚ which was delivered into the wound in the usual fashion; 2-0 Vicryl suture was used to

chambers. The cardiac cycle is controlled by electrical waves that spread throughout the heart. The blood flows into the heart straight into the atria via the vena cava and pulmonary vein. A wave of electrical activity is firstly spread from the Sino-atrial node which spreads across both atria‚ this causes the atria to contract which forces blood down into the ventricles through the atrioventricular valves. The atrioventricular septum prevents the wave crossing the ventricles. The wave passes to the

Lab 34b Cardiovascular Physiology 1. What was the baseline heart rate for the frog? 59-63 bpm 2. Which wave is larger‚ the one for atrial contraction or the one for ventricular contraction? Why? Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? The time during the relaxation part of cardiac cycle. 4. By clicking the Multiple
