Patients with heart rhythm disturbances that require treatment are typically referred by their physician to a cardiac electrophysiologist, a specially trained and certified cardiologist. Download our arrhythmia service brochureâ  types of arrhythmias atrial fibrillationâ  atrial flutterâ  supraventriculartachycardia â  ventricular tachycardia â  treating arrhythmiasâ  atrial fibrillation atrial fibrillation is the most common cardiac arrhythmia, affecting approximately 10 percent of people over the age of 80. generic viagra online next day delivery It is becoming increasingly common in the younger population, however, and lahey cardiologists commonly treat atrial fibrillation in patients in their 40s and 50s. Risk factors the most common risk factor for the development of atrial fibrillation is a history of hypertension. buy viagra usa Other forms of heart disease, such as valvular heart disease and heart failure, are also associated with this type of arrhythmia. buy viagra usa The most common non-cardiovascular cause of atrial fibrillation in this country is alcoholism. Although alcohol abuse is widely recognized as a cause of liver disease, both binge drinking and chronically high levels of alcohol consumption can also lead to atrial fibrillation. Some patients experience atrial fibrillation without any underlying heart disease or other predisposition. viagra online overnight More aggressive forms of therapy are being developed for these patients because they are often relatively young and experience severe symptoms. buy viagra usa There are two main concerns regarding atrial fibrillation. discount online viagra The first is the risk for blood clot formation in the heart, which may lead to stroke or other complications. cheap quality viagra Blood clot risk is related to the age of the patient as well as the presence and severity of underlying heart disease. The second concern is that long-standing fast heart rates may lead to weakening of the heart muscle. buy discount viagra Such weakening is irreversible in some situations, particularly in patients who experience little or no symptoms from atrial fibrillation, despite having very rapid heart rates. Assessment and treatment patients should be assessed on an individual basis for risk factors related to atrial fibrillation and the formation of blood clots in the heart. These risk factors include: being age 65 or older experiencing a previous stroke or transient stroke symptoms having a history of hypertension or diabetes if such factors are present, the main therapy is warfarin (coumadin). buy viagra usa We know from clinical trials that aspirin and other less powerful blood thinners are not effective stroke preventers in patients with significant risk. generic viagra online canada Another important aspect of atrial fibrillation treatment includes controlling heart rate, which is often quite rapid. Heart rate control may be achieved with medications such as beta-blockers or calcium channel blockers. viagra over the counter Catheter ablation and pacemaker therapy are reserved for patients who do not respond to or tolerate these medications. In addition, anti-arrhythmic drugs have been used to maintain a. buy viagra usa Subscribe to Virtual Instruments Magazine Digital EditionContact VI MagVirtual Instruments Magazine
