Cardiac Arrest
Cardiovascular System • Cardiac arrest is the cessation of cardiac mechanical activity. Rhythms: VF (shockable), pulseless VT (shockable), PEA, asystole. High-quality CPR and early defibrillation are critical.
Pulmonary Embolism
Cardiovascular System • Pulmonary embolism is obstruction of pulmonary vasculature, usually from DVT. Massive PE can cause obstructive shock and cardiac arrest. Risk stratified by hemodynamic stability.
Ventricular Tachycardia
Cardiovascular System • Ventricular tachycardia (≥3 consecutive PVCs at ≥100 bpm) can be pulseless (treat as cardiac arrest) or with pulse. Unstable VT requires synchronized cardioversion.
