The cardiac pump is thrown out of gear‚ and the last of its vital energy is dissipated in a violent and prolonged turmoil of fruitless activity in the ventricular walls." He also describes the electrical stimulation of the heart in cases of "fatal syncope" in man. "A single induction shock readily causes a beat in an inhibited heart‚ and a regular series of induction shocks (for example‚ sixty or seventy

Steven Ofstedahl BI 243 Short report Cardiac Arrest The circulatory system along with the heart make are what make up the cardiovascular system. The heart works as a pump that pushes blood to tissues‚ organs and cells in your body. The blood can be pumped throughout the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away

The U wave most often is in the same direction of the T wave with less amplitude. Abnormal U waves are associated with conditions such as hypokalemia‚ diabetes‚ ventricular hypertrophy‚ and cardiomyopathy. Heart Rate and Pulse Rate Heart rate is the number of QRS complexes present in a minute. Pulse rate is the rate of perfusion of blood to the tissue Heart rate is not always the same as pulse rate Calculating

Subendocardial: involving a small area in the subendocardial wall of the left ventricle‚ ventricular septum‚ or papillary muscles. The subendocardial area is particularly susceptible to ischemia.[13] In addition‚ ST depression is seen on ECG. In the clinical context‚ a myocardial infarction can be further subclassified into a ST elevation MI (STEMI)

Digoxin is also used to treat atrial fibrillation‚ a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart). Important information about digoxin You should not use this medication if you are allergic to digoxin‚ or if you have ventricular fibrillation (a heart rhythm disorder of the ventricles‚ or lower chambers of the heart that allow blood to flow out of the heart)

Title: Safety of clonidine and quetiapine in post-cardiac surgery intensive care unit patients Purpose: Critical care of the cardiac surgical patient is a challenging and dynamic topic that requires a multidisciplinary team to ensure patient safety. Moreover‚ clonidine and quetiapine are commonly used agents in intensive care unit (ICU) settings. However‚ the safety of these agents in cardiac surgery patients is yet to be established. Hence‚ our goal is to assess the safety of oral clonidine and
