Calcium channel blocker toxicity. Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs), either by accident or on purpose. [3] This often causes a slow heart rate and low blood pressure. [1] This can progress to the heart stopping altogether. [2]
Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [ 11 ][ 1 ] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose consciousness.
A 2012 study published in the American Heart Association's journal Circulation found that Tasers can cause "ventricular arrhythmias, sudden cardiac arrest and even death." At least 49 people died in 2018 in the US after being shocked by police with a Taser. [3] [4] [5]
Women more often present without chest pain and instead have neck pain, arm pain or feel tired. [11] Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. [12] An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. [3] [4] Most MIs occur due to coronary artery disease. [3]
Researchers analyzed data from 259 women and 996 men in the Netherlands who survived at least 30 days after a cardiac arrest that took place outside a hospital between 2009 and 2015.
Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias. [ 4 ] This includes ventricular tachycardia, ventricular fibrillation, and wide complex tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia. [ 4 ] Evidence in cardiac arrest, however, is poor. [ 5 ]
Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Advanced cardiac life support, advanced cardiovascular life support (ACLS) refers to a set of clinical guidelines established by the American Heart Association (AHA) for the urgent and emergent treatment of life-threatening cardiovascular conditions that will cause or have caused cardiac arrest, using advanced medical procedures, medications, and techniques.
