For which cardiac rhythm and other problems is CPR required?
The two most common heart rhythms that require CPR is ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an extremely rapid cardiac rhythm and ventricular fibrillation is an abnormal cardiac rhythm. For an adult, if the person is unconscious and not breathing, CPR is required. There are numerous reasons an adult would be unconscious and not breathing; all require CPR.
Which heart rhythm often converts to ventricular fibrillation?
Ventricular Tachycardia
What is a ventricular tachycardia?
Ventricular tachycardia-- A rapid heart beat, usually over 100 beats per minute.
Which term describes a rapid heart beat that begins with ventricles?
The condition of irregular quivering of the atria and rapid ventricular heartbeat is atrial fibrillation, or a-fib. While serious, a-fib is not immediately life threatening.
What does arrhythmia mean?
A condition in which the heart beats with an irregular or abnormal rhythm. Could be PVCs (Premature Ventricular Contractions), slow heart rate (<60 bpm = bradycardia), fast heart rate (>100 bpm = tachycardia), atrial fibrillation, and more
What does nonsustained ventricular tachycardia mean?
Nonsustained ventricular tachycardia is elevated heart rate originating in the ventricles that stops on its own.
What is the physiology of ventricular tachycardia?
A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is the medical term meaning abnormal heart rhythm that causes the ventricles to quiver?
Atrial fibrillation is the medical term meaning the irregular, uncoordinated, ineffective twitching contraction of the walls of the atria. A related condition is ventricular fibrillation, which occurs in the lower chambers of the heart.
Why is bretylium in crash cart?
arrhythmia - abnormal electrical pattern of the heart (abnormal ekg/ abnormal heart rhythm) anti-arrhythmics - medications intended to restore normal electrical heart pattern bretylium, in an emergency setting, is an anti-arrhythmic agent used in treating ventricular fibrillation and/or ventricular tachycardia. Sometimes a patient's heart will present with one of these arrhythmias. in these cases, anti-arrhythmics are used in conjunction with defibrillation (shocking) in attempt to restore normal electrical patterns in the heart. anti-arrhythmics, such as bretylium and amiodarone, can also be used in a drip setting for patients who have converted back into a normal heart rhythm for arrhythmia prevention. shane, NREMT-Paramedic, CCP
What part of the heart causes ventricular tachycardia?
AV node
What is sinus rhythm with occasional premature ventricular complexes?
Sinus rhythm, the natural beating of the heart begins in the sinoatrial (or sinus) node and is located in the wall of the right atrium. Occasional premature ventricular complexes are abnormal heartbeats that disrupt the regular rhythm of the heart. The irregular heartbeats begin in one of the ventricles in the lower part of the heart.
