IT WAS PROPER TO TERMINATE THE TREADMIL TEST. WHEN THE HEART GOES INTO V TACH THERE ISN'T ENOUGH TIME DURING DIASTOLE (FILLING PHASE) TO ADEQUATELY FILL THEREBY REDUCING CARDIAC OUTPUT.
REDUCED CARDIAC OUTPUT (AMOUNT OF BLOOD PUMPED OUT IN A MINUTE) ENGAGES COMPENSATORY PROCESSES THAT INCLUDES CONSTRICTING VESSELS AND INCREASING BLOOD PRESSURE AND HEART RATE (V TACH IS ALREADY A FAST HEART). THE HEART IS UNDER A LOT OF STRESS AS IT NOW HAS TO PUMP AGAINST HIGHER RESISTANCE TO BLOOD FLOW.
THERE MAY NOT BE SYMPTOMS BUT THE SIGNS MONITORED DURING THE TEST IS CAUSE FOR CONCERN.
