What is Arrhythmia?

An irregular heartbeat means that you have an arrhythmia. Well, this kind of condition can be prevented, too, but if not taken care of properly can lead to the ultimate death of a person.

People suffering from this condition may experience a quick or slow heartbeat. However, the beating rhythm will be irregular.

This condition occurs when the electrical signals coordinating with your heartbeats malfunction.

Many types of these conditions are known to doctors, who think some are harmless.

But, if the heartbeat shows a high level of irregularity, then it results from a weak heart and can cause severe pain or injury to the person.

When symptoms start showing, a person, he/she needs to visit a doctor immediately, or else serious complications may occur.

Some symptoms faced by people with this type of condition are weakness in their body, dizziness, experience frequent fainting, heart beating rapidly, shortness of breath, pain in the chest, and in extreme cases, the patient may die due to cardiac arrest.

According to the American Heart Association (AHA), a person must have a heartbeat count of 60-100 beats per minute.

There are several methods to check a person’s heartbeat, like touching the wrists, inside the elbows, the side of the neck, and the top of the foot. So, do the counting, and if you see some irregularity, visit a doctor immediately.


What is Dysrhythmia?

Dysrhythmia is yet another term that has the same meaning.

This is also the term used for an irregularity in a heartbeat. Whenever a person suffers a condition that falls under this category, they have dysrhythmia.

The heartbeat rate can be either slow or fast than the normal heartbeat rate. However, both cases show irregularity and need a medical check-up.

Treatments should be made for those suffering from this condition because if the situation worsens, it may cost you your life.

The causes of this condition are the same as the causes of arrhythmia.

Some causes of this type of condition are high blood pressure, muscle change in the heart vessel, disorders in heart valves, previous experience of a heart attack, and other medical-related conditions.

However, unhealthy people also might suffer from this condition.

For those who are chain smokers, heavy drinkers, have a habit of eating junk food or do not exercise regularly, please make sure that you change your lifestyle to a healthy one.

 You keep yourself healthy by maintaining a healthy lifestyle.

If you ever notice pain in your chest, shortness of breath, or any other symptoms, please visit a doctor immediately because the more you leave it untreated, the more dangerous it is for you.
