Atrial Fibrillation And The Link To Having A Stroke Dr. Graham Wong, MD, MPH, FRCPC, FACC, Cardiologist

Atrial fibrillation is an irregular heartbeat, also called an arrhythmia, that can increase your risk of heart failure, stroke, blood clots and other heart conditions. A normal heart contracts and relaxes to a regular beat, but if you have atrial fibrillation, the atria (upper chambers) beat out of sync with the ventricles (lower chambers). This can cause blood to pool in your atria, causing blood clots that travel to your brain and cause a stroke.

How is a Pacemaker Placed in the Body? Dr. Graham Wong, MD, MPH, FRCPC, FACC, Cardiologist

A cardiac pacemaker is the natural pacemaker of your heart, which controls your heart rate. An artificial pacemaker is a small device that’s surgically placed under the skin of the chest and uses electrical pulses to help control your heartbeat. People with an arrythmia (irregular heartbeat) may require a pacemaker. An arrythmia can be caused by a heartbeat that's too fast (tachycardia) or too slow (bradycardia).

Heart Attack Medications and Side Effects Dr. Graham Wong, MD, MPH, FRCPC, FACC, Cardiologist

As you know, all drugs have side effects, but some are more common than others. With respects to the blood-thinning drugs, whether it be Clopidogrel, Aspirin, prasugrel, or ticagrelor, if a drug thins your blood, the most common side effect would be bleeding.
