Ventricular fibrillation fatal?

Ventricular fibrillation fatal?

Possibly..: In ventricular fibrillation, vfib, the heart is quivering and there is no blood flow so the person is clinically dead. If the heart cannot be restored to a rhythmn where there is blood flow, the patient will then be pronounced dead. Treatment for this rhythmn includes electrically shocking the heart as quickly as possible. Performing CPR in the meantime can be life-saving. ...Read more

Abnormal Heart Rhythms (Definition)

Abnormal heart rhythm is a condition in which a person has an abnormal heartbeat pattern, as detected by an EKG (electrocardiogram) of the heart. Some abnormal rhythms run in families (hereditary abnormal rhythms). Some abnormal rhythms are not dangerous, while others can cause ...Read more

New onset Cardiomyopathy. Risk for Sudden Cardiac Death and Ventricular Tachycardia.....?

New onset Cardiomyopathy.  Risk for Sudden Cardiac Death and Ventricular Tachycardia.....?

Needs rapid evaluation: Although chronic hypertension is among the most common causes of nonischemic cardiomyopathy, there appears to be no hypertensive history in this case. With an ejection fraction of 20%, sudden life-threatening arrhythmia is a significant risk. An implantable defibrillator must be considered urgently. A Zoll Vest could be considered if there is any delay in implanting a defibrillator. In addition, consideration should be given to a myocardial biopsy to search for an infiltrative cardiomyopathy. Diuretic, beta blocker and vasodilator therapy might be limited by a low blood pressure. If there is a wide QRS, resynchronization with a biventricular pacemaker might help restore ventricular function. The prognosis (and treatment) will be dependent upon the underlying cause of the cardiomyopathy. ...Read more

Heart problems ventricular bigeminy?

Heart problems ventricular bigeminy?

Usually benign: Premature or "skipped" beats frome the bottom chambers of the heart are common; they sometimes occur in fixed patterns. When every other beat is a premature beat, it's called ventricular bigeminy. When every 3rd beat is premature, it's called ventricular trigeminy, and so on. Bottom line: with a normal heart, these patterns are completely benign and don't need treatment unless very troubling. ...Read more

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Is ventricular fibrillation the cause of cardiac arrest?

Is ventricular fibrillation the cause of cardiac arrest?

One of them: It is the most common heart arrhythmia associated with cardiac arrest. It is not exact to call it the cause, since ventricular fibrillation itself has an underlying cause, most commonly coronary artery disease, but there are others. ...Read more

Can a cardiac arrest cause respiratory failure?

Can a cardiac arrest cause respiratory failure?

Yes...: Cardiac arrest means that the heart is no longer beating. When the heart stops, breathing also stops, called a respiratory arrest. However, a person can stop breathing even though their heart is still beating; the reverse cannot be true! ...Read more

Can propranolol cause cardiac arrest?

Can propranolol cause cardiac arrest?

Cardiac arrest: Propranolol in extremely high dose might be able to cause bradycardic cardiac arrest. In the usual dose ranges that happenstance is unlikely. Tachycardic cardiac arrest is unlikely on propranolol. ...Read more

Cardiac Arrhythmia (Definition)

The normal heart beat starts in the sinus node of the right atrium. An arrhythmia is when the heart beats too fast, too slow, starts in a different place, or if the electrical activity of the heart circulates through a different pathway ...Read more
