A normal heart (Maintenance of an Isometric ST-segment during exercise is the response of a normal heart). • The sensitivity of a routine ETT is effort dependent. What physiological changes occur during effort in the routine ETT? Increased coronary flow and increased systolic blood pressure (The physiological changes that occur during effort in the routine ETT are increased coronary flow and increased systolic blood pressure). • The diagnostic accuracy of stress testing is decreased among women compared to men for what reasons? Women usually have single vessel or non-obstructive disease (The diagnostic accuracy of stress testing is decreased among women compared to men because women usually have single vessel or non-obstructive disease). • Ter What do you know regarding ischemia that is confined to only the posterior and or lateral segments of the left ventricle? m Definitio Difficult to detect by ETT (Ischemia that is confined to only the posterior and or lateral segments of the left ventricle is difficult to detect by ETT, but that does not mean that ETT cannot detect ischemia limited to these functional areas of the heart). n • Your preceptor decides to add Doppler Flow studies to the echocardiogram exercise test for a patient with a recent history of a holistic murmur best auscultated at the left sternal boarder. The patient has no history of cardiac surgeries. He asks you what might be the main advantages of adding Doppler Flow for this particular patient. You know from your readings that there are several reasons to add Doppler Flow and below are listed more than one correct reason.

Still, you know that the ETT is the preferred test for CAD. You consider adding a pharmacological agent to get to maximum heart rate. What agent would be the most commonly used agent to assist in an ETT? Dobutamine (The pharmacological agent most commonly used to assist in an ETT is dobutamine). • Medicare covers inpatient hospital services under which part of the Medicare insurance? Part A (Medicare covers inpatient hospital services under Part A). • Medicare hospital insurance (Part A) is funded through what system?
