PVCs may be found incidentally on cardiac tests such as a 12-lead electrocardiogram (ECG/EKG) performed for another reason. In those with symptoms suggestive of premature ventricular complexes, the ECG/EKG is the first investigation that may identify PVCs as well as other cardiac rhythm issues that may cause similar symptoms.
The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia. Other potential causes include: Heart tissue scarring from a previous heart ...
The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
It is a form of cardiac arrhythmia in which ectopic foci within either ventricular or atrial myocardium, or from finer branches of the electric transduction system, cause additional beats of the heart. Some medications may worsen the phenomenon. [citation needed] Ectopic beats are considered normal and are not indicative of cardiac pathology.
Cardiac arrest results from electrical disturbances that cause the heart to suddenly stop beating the way it should. In cardiac arrest, death can result quickly if steps aren’t taken right away.
In young athletes, Panhwar notes that a common cause of cardiac arrest is hypertrophic cardiomyopathy (abnormally thickened heart muscle), in which intense physical activity can cause cardiac ...
Its use is recommended in those who have a serious dysrhythmia, are in cardiac arrest, or have a potassium of greater than 5 mmol/L. [1] Low blood potassium or magnesium should also be corrected. [1] Toxicity may reoccur within a few days after treatment. [1] In Australia in 2012 there were about 140 documented cases. [1]
If a life-threatening arrhythmia is detected, the device can deliver a small electric shock to terminate the abnormal rhythm and restart the heart. [1] Implantable defibrillators are often recommended for those with CPVT who have experienced blackouts, ventricular arrhythmias or cardiac arrest despite taking appropriate medication. [2]
