Correct Answer is B
Explanation
associated with chronic heart failure. Activation of the RAAS system occurs as a compensatory mechanism in response to decreased cardiac output and reduced renal perfusion. The renin-angiotensin-aldosterone system increases blood pressure, maintains blood volume and improves cardiac contractility in the short term, but in the long term it can lead to fluid retention, edema, and worsen cardiac function.
Correct Answer is C
Explanation
In the normal electrocardiogram, the PR interval represents
The PR interval represents the time from the onset of atrial activation to the onset of ventricular activity. During this time, the electrical impulse travels through the atria, the atrioventricular (AV) node, and the bundle of His before entering the ventricles and initiating ventricular depolarization. Option A is incorrect because the atrial depolarization is represented by the P wave. Option B is incorrect because the ventricular depolarization is represented by the QRS complex. Option D is incorrect because there is no such term as “electrical systole” of the ventricles in ECG interpretation.
