Causes of heart arrhythmia

Heart arrhythmia is the scenario where the heart beats at an irregular pace or pattern, sometimes more than a 200 beats per minute or sometimes as low as 50-60 per minutes.

The causes of arrhythmia can be divided into two categories. Primary rhythm disturbances, which not associated with any underlying heart disease and secondary rhythm disturbances, arise from existing heart conditions.

Primary rhythm disturbances such as:
*Smoking
*Excessive use of alcohol or caffeine
*Drug abuse
*Some prescription medications and herbal remedies

While secondary rhythm disturbances including:
*Heart defects at birth
*Electrolyte imbalances in your blood (such as sodium or potassium)
*Changes in your heart muscle
*Injury from a heart attack
*Stress
*Healing process after heart surgery
*Irregular heart rhythms can also occur in "normal, healthy" hearts.

Risk factors include: coronary artery disease; high blood pressure, high blood cholesterol levels, unhealthy lipid or triglyceride blood levels; atherosclerosis, diabetes, thyroid-gland orders; and damaged heart valves.

Cerebrovascular disease

Cerebral vascular disorders are characterized by sudden neurologic deficits resulting from ischemia or hemorrhagic events.

Cerebrovascular disease is one of the most common neurologic diseases, with a relatively high cases fatality ratio and a substantial personal, familial and social impact among the survivors.

Cerebrovascular disease is the third leading cause of death and the leading cause of disability in the United States.  Many different cerebrovascular diseases may cause cognitive decline and dementia, including stroke, silent infarcts, ischemic white matter lesions, hereditary cerebral hemorrhage with amyloidosis, granular cortical atrophy, hypertensive encephalopathy, cerebral amyloid angiopathy and cerebral vasculitis.

The major risk factors for the development of cerebrovascular disease are hypertension and diabetes.

Other risk factors include atherosclerosis, inflammatory processes, dissecting aneurysm, disorders affecting the myocardium, congestive heart failure, polycythemia, cigarette smoking, use of oral contraceptives and postpartum infection.
