Abstract:
Sequential injections of different contrast material in the canine coronary artery were performed while ventricular pressure and EKG were recorded. Larger volumes of contrast material caused more fibrillation and more drop in pressure. Preliminary myocardial infarction increased pressure effects. Diatrizoate methylglucamine (Renografin-76) caused more fibrillation and lowering of ventricular pressure than iothalamate or metrizoate Coronar. Calcium lessened the ventricular pressure depression from iothalamate.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:30Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
