Question

On admission, a 12-lead ECG has been ordered. Which of the following options best describes the rationale for undertaking a 12-lead ECG in Mr Kwon’s situation?

Select one:
Stroke causes life-threatening ventricular fibrillation.
A 12-lead ECG is routinely prescribed for all patients presenting to hospital acutely unwell.
A 12-lead ECG directly examines cardiac output.
A 12-lead ECG will determine the existence of atrial fibrillation, which is a common and manageable risk factor for stroke in older people.

Answer 1

Opion D- 12-lead ECG will determine the existence of atrial fibrillation, which is a common and manageable risk factor for stroke in older people.

ECG is the graphical representation of electrical activity of heart.For proper understanding of The electrical activity of heart 12 ECG leads are used.

Stroke is Cerebro Vascular Accident-The condition in which blood supply to blood is reduced or absent.

Atrial Fibrillation -this is the condition in which there is contraction of Atria more than normal-Which may lead to irregular heartbeat (arrhythmia) --causing blood clots leading to stroke

In atrial Fibrillation,Blood is not properly pumped out of the heart, which may lead to pooling of blood and formation of clot. This clot may travel to the brain and block bloodflow to part of the brain leading to a stroke.

So,ECG is Important in stroke patients to identify cause of stroke like Atrial fibrilation
