What percentage of ventricular filling is passive and how much is atrial kick? -
ANSWER Passive: 75%
Atrial kick: 25–35%
What are the three components that make up stroke volume? - ANSWER
Preload
Afterload
Contractility
Uses of Beta Blockers - HTN
Classic angina (coronary artery blockage)
Ventricular and supraventricular arrhythmias
ACS
Heart failure.
Hypertrophic cardiomyopathy.
Clinical effects of beta blockers - ANSWER: Reduced heart rate
Decreased contractility
Decreased automaticity
, Decreased conduction velocity
Reduced renin release (kidneys)
Cardioselective beta blockers inhibit beta 1 receptors.
N-AMEBA
Nebivolol
Atenolol
Metoprolol**
Esmolol
Bisoprolol**
Acebutolol
**are usually used in individuals with CHF with co-morbid COPD or asthma.
Alpha/Beta Blockers - ANSWER Labetalol for HTN emergency.
Carvedilol—Heart failure
Nonselective beta blockers – Block Beta 1 and Beta 2 blockers.
Propranolol
Sotalol
