Quiz zum Vortrag
What is the correct conduction pathway from initial pacemaker to ventricular contraction?
- SA node → AV node → Bundle of His → Purkinje fibers
- AV node → SA node → Purkinje fibers → Bundle of His
- Bundle of His → SA node → AV node → Purkinje fibers
- Purkinje fibers → Bundle of His → AV node → SA node
- AV node → Bundle of His → SA node → Purkinje fibers
If stroke volume is 70 mL and heart rate is 80 beats/min, what is cardiac output?
- 5.6 L/min
- 4.0 L/min
- 3.5 L/min
- 6.4 L/min
- 7.0 L/min
Which definition correctly describes preload?
- Ventricular stretch from filling
- Strength of myocardial contraction
- Resistance against ventricular ejection
- Speed of electrical conduction
- Arterial blood pressure
Blood pressure is defined as which relationship?
- Cardiac output × systemic vascular resistance
- Heart rate × stroke volume × preload
- Contractility × preload × afterload
- Stroke volume ÷ vascular resistance
- Heart rate ÷ systemic vascular resistance
