Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...

Anemia - Answer-Reduction of the quantity of red blood cells or hemoglobin. Angina pectoris - Answer-Chest pain with the feeling of suffocation usually due to deficiency of blood supply to the myocardium resulting in ischemia to the myocardium, caused by poor coronary circulation. Anticholinergic - Answer-A drug that counteracts the action of ecetylcholine, the neurotransmitter of the parasympathetic nervous system and thereby counteracts the parasympathetic nervous system. Antiemetic - Ans...

Dysrhythmia - cORRECT sOLUTION Any disorder of the heart beat or heart rhythm. Cardiac output is impaired. Cellular oxygenation is then also impaired Electrical problem will definitely effect the mechanical but a mechanical problem may not effect the electrical. Explaining dysrhythmias - cORRECT sOLUTION -Classified to their site of origin -SA node atrial tissue, AV node, junctional tissue (tissue around AV node), and ventricular tissue -Caused by a disturbance in impulse formation ...
