A 82 year old client presents to the emergency room with dizziness, weakness, and palpitations. His heart rate is 152. The nurse demonstrates an understanding of EKG changes that occur in the elderly when she makes what correct statement about the client’s condition?
A
Ventricular fibrillation is a common arrhythmia in older patients.
B
It is normal for an aging heart to go into complete heart block.
C
Atrial fibrillation is a common dysrhythmia in older patients.
D
Sinus bradycardia can occur due to decreased baroreceptor reactivity.
Explanation: 

Detailed explanation-1: -The cause of palpitations can be determined in the majority of patients. The most common causes of palpitations include cardiac disorders, medical conditions including endocrine and metabolic abnormalities, psychiatric disorders, medication effects, and drug or other substance use effects (table 1).

Detailed explanation-2: -Palpitations-sensations of a rapid or irregular heartbeat-are most often caused by cardiac arrhythmias or anxiety.

Detailed explanation-3: -Both bradycardia and tachycardia can precipitate dizziness, and the arrhythmia is more commonly supraventricular than ventricular[4].

Detailed explanation-4: -Atrial fibrillation, often called AFib or AF, is the most common type of treated heart arrhythmia. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way.
