…lining (epicardium). These layers are analogous to tunica intima , tunica media , and tunica adventitia , respectively. Figure 1. Layers of the left ventricular wall, pericardium and…

…radiotracers emit gamma photons directly. These gamma rays are detected by gamma cameras to create tomographic images of the left ventricle. In PET (Positron Emission…

…defined as a diameter reduction of at least 50%. Severe proximal disease of both the proximal left anterior descending and proximal left circumflex arteries may…

…first half of the P wave is therefore a reflection of right atrial activation and the second half is a reflection of left atrial activation…

…to describe a reduction of blood flow to tissues and organs. A few decades later Cohnheim demonstrated that ligation of the left anterior descending artery…

…with or without left ventricular hypertrophy. Among patients with NSTE ACS undergoing angiography, approximately 10% have no critical epicardial stenosis. In some of these patients…

…change (% reduction) in left ventricular diameter during systole. It is considered a poor measure of systolic function; it is only reliable if the left ventricle…

…left ventricle is usually considerably larger than the right ventricle, the QRS complex is actually a reflection of the electrical potentials generated by the left…

Echocardiography Generating the ultrasound image The ultrasound transducer generates short bursts (pulses) of ultrasound waves. Reflected ultrasound waves are analyzed by the machine during the…

…the left ventricle is many times larger than the vector generated by the right ventricle, the QRS complex is actually a reflection of left ventricular…
