Q2: Define arrhythmia. Discuss the etiology and pathophysiology of i) bradycardia, ii) tachycardia.

Answer 1

Answer: Hypertension is the condition in which there is increased blood pressure on the wall of arteries . There are several reasons of the hypertension. It involves changes in autonomic nervous system.

Some of the causes are:

• Obesity
• Cardiovascular disease
• Lack of physical activity.

The sign and symptoms of hypertension are:

1. Fatigue
2. Blurred vision
3. Vomiting
4. Pain in the chest
5. Increased heart rate.

Arrhythmia is a condition in which the heart rate becomes too low or too fast. This condition occurs due to various reasons such as cardiac disease, hypertension etc.

The bradycardia is condition of too low heart rate as compared to the normal. The cause of this condition is abnormality in the SA node. As due to this abnormality in the heart, the heart doesn't allow the electric impulse to pass through. Hence there is low heart rate.

Tachycardia is condition where heart rate increases due to excessive exercise, myocardial infarction , stress, trauma or illness. Symptoms includes such as increased heart rate, palpitations etc.
