HF Stroke SCD

3
Q

BB/NDCCB mechanism for management?

A

Decrease contraction and increase diastole period–decrease LVOT also, decrease anginal symptom NDCCB if symptom persist despite CCB

4

complication?

A

Stroke(C.artery) AAR(root dilation) Horner syndrome(carotid sympathetic plexus injury) MI: Ostia obstruction Pericardial effution(pericardium) Hemothorax (pleural cavity) Renal injury: renal arteries Abdominal pain: mesenteric ischemia LE paraplegia (spinal arteries)

9
Q

Is atherosclerosis is the risk?

A

Yes but not be as a single cause is usually found in a patient with thoracic and abdominal aneurythm

10
Q

ECG future of Hypertrophic cardiomyopathy?

A

Tall long R wave in aVL and deep S wave in V3 Defect in depolarization in the anterior lead (I,aVL, V4,V5, and V6)

ECG feature?

A

I–(progressive PR prolongation with dropped QRS wave follow P wave at the end (grouped beat) and narrow QRS

II-PR interval remains the same but some unconducted p wave(dropped QRS with narrow(but wider than I) or wide QRS.
