How do tachycardia and bradycardia affect cardiovascular hemodynamic performance in a lumped parameter mathematical model?
A lumped parameter mathematical model demonstrates that tachycardia significantly reduces capillary blood flow, providing a computational tool for simulating cardiovascular hemodynamics.
Abdi et al. (2014) studied Tachycardia and bradycardia. Tachycardia and bradycardia simulation vs. Normal heart rate simulation (75 bpm) was evaluated on Capillary blood flow and hemodynamic performance. Mathematical modeling demonstrated that simulated tachycardia (150 beats/minute) leads to a significant reduction of capillary blood flow to less than 100 ml/s compared to normal heart function.
