Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat. Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat , or normal heartbeat.
Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. [6] Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or defibrillation. [6] Arrhythmia affects millions of people. [4]
Treatment of severe toxicity is with digoxin-specific antibody fragments. [1] 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]
Three risk factors — high blood pressure, smoking and atrial fibrillation (which is an irregular heart rhythm) were linked with higher risk of severe compared to mild-moderate stroke,” said Dr ...
The weakness may also lead to ventricular aneurysm, a localized dilation or ballooning of the heart chamber. [citation needed] Risk factors for myocardial rupture include completion of infarction (no revascularization performed), female sex, advanced age, and a lack of a previous history of myocardial infarction.

Premature ventricular contraction in an ECG (arrows) of a dog, caused by dilated cardiomyopathy. Premature ventricular contractions occur in healthy persons of any age, but are more prevalent in the elderly and in men. [3] In a very significant proportion of people they occur spontaneously with no known cause. [citation needed]
Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
