INTRODUCTIONINTRODUCTION

Now-a-days heart related diseases are on the rise.Now-a-days heart related diseases are on the rise.

According to WHO,16 million people around the According to WHO,16 million people around the world each year died of CVD and around 20 million world each year died of CVD and around 20 million people are at the risk of sudden heart failure[6].people are at the risk of sudden heart failure[6].

ECG of patients with cardiac arrhythmia need to be ECG of patients with cardiac arrhythmia need to be monitored continously .monitored continously .

ECG(ELECTROCARDIOGRAM)ECG(ELECTROCARDIOGRAM)

It is the recording of electrical potential It is the recording of electrical potential produced by the excitation of cardiac muscle.produced by the excitation of cardiac muscle.

Normal ECG results:Normal ECG results:

Heart rate: 60 to 100 beats per min.Heart rate: 60 to 100 beats per min.

Heart rhythm: consistent and even.Heart rhythm: consistent and even.

CARDIAC ARRHYTHMIA:CARDIAC ARRHYTHMIA:

It is the disturbances(abnormalities) in the It is the disturbances(abnormalities) in the heart rhythm.heart rhythm.

Bradycardia: slow heart rate(below 60 Bradycardia: slow heart rate(below 60 beats/min)beats/min)

Tachycardia: fast heart rate(above 100 Tachycardia: fast heart rate(above 100 beats/min)beats/min)

Atrial Fibrillation: irregular heart rhythm.Atrial Fibrillation: irregular heart rhythm.
