A heart-beat rate that is over 100 beats a minute is medically termed Tachycardia, this condition is very dangerous to humans. Varieties of irregular heart rhythms also known as arrhythmias are potent enough to cause tachycardia.
What Causes a Racing Heart?
Medically, a normal heart beat should be 60—100 times every minute. When your heart beats more than 100 times each minute, that’s considered high (called tachycardia in the medical world). Fast heartbeats can last for seconds to hours.
Please note that not all cases of a racing heartbeat are dangerous; however, it is important to understand that so many of our everyday activities that are not even related to heart problems can cause someone’s heart to race faster. And below are some of these everyday activities:
• low blood sugar
• low blood pressure
• fevers and anemia
• pregnancy or menstruation
• heavy exercise
• panic attacks
• too much alcohol
• too much caffeine
• excess nicotine
• illegal drugs
However, if tachycardia is left checked or untreated, some forms of tachycardia can lead to serious health complications such as heart failure, stroke or sudden cardiac arrest and death.
Treatment for tachycardia may include specific maneuvers, medication, cardio version or surgery to control a rapid heartbeat.
Types of tachycardia
Researchers have sown that there are many different types of tachycardia. Sinus tachycardia refers to a typical increase in the heart rate often caused by exercise or stress. Don’t miss reading 10 Proven Tips To Help You Eat Healthier
Other types of tachycardia are grouped according to the part of the heart responsible for the fast heart rate and the cause. Common types of tachycardia caused by irregular heart rhythms (arrhythmias) include:
1. Supraventricular tachycardia (SVT)
Supraventricular tachycardia is a broad term that includes arrhythmias that start above the ventricles. Supraventricular tachycardia causes episodes of a pounding heartbeat (palpitations) that begin and end abruptly.
2. Ventricular fibrillation
Rapid, chaotic electrical signals cause the ventricles to quiver instead of contracting in a coordinated way. This serious problem can lead to death if the heart rhythm isn’t restored within minutes. Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning.

3. Atrial fibrillation (A-fib)
This is the most common type of tachycardia. Chaotic, irregular electrical signals in the upper chambers of the heart (atria) cause a fast heartbeat. A-fib may be temporary, but some episodes won’t end unless treated.
4. Atrial flutter
Atrial flutter is similar to A-fib, but heartbeats are more organized. Episodes of atrial flutter may go away themselves or may require treatment. People who have atrial flutter also often have atrial fibrillation at other times.

5. Ventricular tachycardia
This type of arrhythmia starts in the lower heart chambers (ventricles). The rapid heart rate doesn’t allow the ventricles to fill and squeeze (contract) to pump enough blood to the body. Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds can be life-threatening.
