Tachycardia is a condition that makes your heart beat more than 100 times per minute. There are three types of it:
Supraventricular. This happens when the electrical signals in the organ's upper chambers misfire and cause the heart rate to speed up. It beats so fast that it can’t fill with blood before it contracts. That reduces blood flow to the rest of your body.
This is a rapid heart rate that starts in your ticker's lower chambers. It happens when...
Most people imagine they would know when they are having a heart attack. It would be difficult not to recognize symptoms of "the big one" – sweating, soreness in the left arm, and sudden, disabling chest pain.
But that’s not always the case. Sometimes the signs are much more subtle or mimic other conditions.
"I have heard of instances when a cardiologist was having a heart attack and thought they were having indigestion," says Elizabeth Jackson, MD, assistant professor of cardiovascular medicine at the University of Michigan Health Systems.
As with any health issue, knowledge is power. And when your heart is on the line, you need all the power you can get.
So here are six major heart health myths and the reality behind them.
Heart Myth #1: I would know if I had high blood pressure or high cholesterol.
Risk factors are usually silent, meaning they have no obvious associated symptoms.
"Hypertension is the silent killer, you are not going to know you have it," says Jennifer Mieres, MD, a cardiologist at North Shore-Long Island Jewish Health System. "When high blood pressure presents as a symptom like headaches or renal failure, it is more difficult to control at that stage. Early treatment is essential to preventing end organ damage, which is often irreversible."
This begins with symptoms. Although many people experience the classic "elephant sitting on the chest" sensation when they have a heart attack, there are also less traditional symptoms, and they are more common among women.
