In an EKG reading: | the P wave corresponds to the AV node firing. the QRS complex corresponds to a time when ventricular pressure is greater than atrial pressure. When in sympathetic mode, the AV Bundle will be receiving impulses at a faster rate then when in parasympathetic mode. | The T wave represents the time when the SA node first fires. The P-R interval represents the delay that occurs when the AV Bundle transmits signals to the Purkinje fibers.
Referencing the ECG trace below, when would you expect the AV node to start depolarizing? options: P R Q S QT Interval T Right before the T wave. Some time during the PR interval. Right before the P wave. Right after the QRS complex. RR Interval P R S QT Interval T

1. Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?
