Cardiac arrest is diagnosed by the inability to find a pulse in an unresponsive patient. The goal of treatment for cardiac arrest is to rapidly achieve return of spontaneous circulation using a variety of interventions including CPR, defibrillation, and/or cardiac pacing.

In those with cardiac arrest due to trauma, CPR is considered futile but still recommended. Correcting the underlying cause such as a tension pneumothorax or pericardial tamponade may help. Pathophysiology. CPR is used on people in cardiac arrest to oxygenate the blood and maintain a cardiac output to keep vital
Jul 25, 2023 · Deb Balzer. July 25, 2023. Cardiac arrest, or sudden cardiac arrest as it is more formally known, is a medical emergency. It happens when an event, usually an electrical disturbance, quickly and unexpectedly causes your heart to stop working. It's not the same as a heart attack and is called sudden because it seems to happen without warning.
Apr 7, 2023 · Cardiac arrest is usually due to underlying structural cardiac disease. Seventy percent of cardiac arrest cases are thought to be due to ischemic coronary disease, the leading cause of cardiac arrest. Other structural causes include congestive heart failure, left ventricular hypertrophy, congenital coronary artery abnormalities, arrhythmogenic ...

Ventricular tachycardia ( V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] . Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Jul 31, 2023 · Cardiopulmonary arrest (CPA) is the cessation of effective ventilation and circulation. It is also known as cardiac arrest or circulatory arrest. In adults, it is most likely to be caused by a primary cardiac event. The most common electrical mechanism which is responsible for 50 to 80% of cardiopulmonary arrest is ventricular fibrillation (VF).
