Cardiac seizures are caused by the disruption of communication between the heart and the central nervous system. Since proper nerve and brain function are necessary in regulating cardiovascular function, a seizure--either epileptic or stress-related--may temporarily create an arrhythmia or arrest of the heart's normal rhythm. Likewise, a cardiac irregularity may disrupt the blood flow to an area of the brain and create a non-epileptic seizure 1.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
In addition, the term "cardiac seizure" may be used to describe a brain or nerve-related disruption that is caused by an interrupted blood flow to one of several different areas of the brain, due to a cardiac event or disorder. Damage to the cerebral cortex and hippocampus, in particular, may lower a person's seizure threshold, making it more likely that they will experience a seizure.
Risk factors for a brain or nerve-related seizure that is caused by a cardiac event include cardiovascular injuries, diseases, incidents, failures, surgeries and medications.cause:

If you see someone who seems to be experiencing any of the symptoms associated with a cardiovascular-induced brain or nerve seizure, turn him on his side, if you can, and move any objects away from him. Do not attempt to place anything into his mouth and do not tie or restrain his hands or legs during the seizure. Loosen any restrictive clothing to keep the seizing person from strangling herself accidentally. If you are able, place cushions or soft blankets under or around the person to help cushion any potential injuries he may receive while thrashing or seizing. Call 911, and describe the type of movement that you are observing in the patient, as well as the length of the seizure. Remain near the person until help arrives.
For cardiac-related symptoms, place the patient in a prone position, with his feet and legs elevated. If the patient is conscious, place a baby or adult aspirin in his mouth and provide a small sip of water, if needed, to help him swallow the pill. If the patient has a prior history of cardiac problems, he may have nitroglycerin tablets. If so, place one under his tongue. Call 911 and remain calm while you provide the necessary information.
If the patient appears to have stopped breathing, attempt CPR if you are trained to do so. Press down hard on his chest area a few times, and breath into his mouth after 30 chest compressions. Continue the compressions and resuscitation uninterrupted until help arrives or until the patient begins breathing again.
To treat a person who appears to be experiencing a stroke, lie him down on his side with a pillow or other soft object supporting his head to help relieve blood pressure in the brain and reduce the chance that he might choke on saliva. Call 911 and describe the symptoms that the person is experiencing. If the person is unconscious, be sure there is nothing in his mouth and carefully turn him onto his stomach, placing his arms under his forehead to support his head. Remain with him until help arrives.
