At this fast a rate, the heart chambers do not have adequate time to refill fully with blood. This is called fibrillation and is associated with a corresponding decrease in cardiac output and lower blood pressure. Since nitroglycerin also causes lower blood pressure by dilating or expanding the vessels, the additive effect could cause loss of consciousness.

You just want to no what causes chest pain after a heart attack?
Chest pain after a heart attack or during a heart attck is caused by constriction of the blood vessels. Your heart needs blood to survive and when the vessels constrict, it limits bloodflow to your heart. This causes intense pain--that is why you are given nitroglycerin tablets. Nitro opens the vessels.

* All patients being transported for chest pain should be managed as if the pain were ischemic in origin unless clear evidence to the contrary is established. * If available, an ALS unit should transport patients with hemodynamic instability or respiratory difficulty. * Prehospital notification by Emergency Medical Services (EMS) personnel should alert ED staff to the possibility of a patient with MI. EMS personnel should receive online medical advice for a patient with high-risk presentation. * The American Heart Association (AHA) protocol can be adopted for use by prehospital emergency personnel. This protocol recommends empirical treatment of patients with suspected STEMI with morphine, oxygen, nitroglycerin, and aspirin. * Specific prehospital care includes the following: * ** Intravenous access, supplemental oxygen, pulse oximetry ** Immediate administration of aspirin en route ** Nitroglycerin for active chest pain, given sublingually or by spray ** Telemetry and prehospital ECG, if available * EMS protocol should be formulated to strongly consider taking patients with suspected MI/ACS, and certainly patients with STEMI, to facilities capable of PCI if geographically possible. * Prehospital thrombolysis allows eligible patients to receive thrombolysis 30-60 minutes sooner than if treatment were given in the ED; however, prehospital thrombolysis is still under investigation.
