Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [12] [1] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.
As the heart beats, these pulses are transmitted smoothly via laminar (non-turbulent) blood flow throughout the arteries, and no sound is produced. Similarly, if the cuff of a sphygmomanometer is placed around a patient's upper arm and inflated to a pressure above the patient's systolic blood pressure , there will be no sound audible.
Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...
According to cardiologist Dr. Siyab Panhwar, “cardiac arrest refers to when the heart suddenly stops beating and comes to a standstill. This is often accompanied by loss of breathing and loss of ...
DENVER — The family of a 4-year-old boy whose heart had stopped beating hours earlier gathered at Children’s Hospital Colorado last month to say their final goodbyes to Cartier McDaniel.
A British woman says it's a "miracle" she's alive after surviving a six-hour cardiac arrest brought on by severe hypothermia.
Patients supported by methods that certainly maintain enough blood circulation and oxygenation for sustaining life during stopped heartbeat and breathing, such as cardiopulmonary bypass, are not customarily considered clinically dead. All parts of the body except the heart and lungs continue to function normally.
Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction" [1] [2]) is the absence of ventricular contractions in the context of a lethal heart arrhythmia (in contrast to an induced asystole on a cooled patient on a heart-lung machine and general anesthesia during surgery necessitating stopping the heart).
