### input:
A COUPLE OF DAYS AGO, I FELT REALLY TIRED AND LAYED DOWN ON THE COUCH TO TAKE A NAP BUT ALL OF A SUDDEN MY HEART FELT LIKE IT STOPPED AND I STARTED TO PASS OUT. JUST BEFORE I BECAME UNCONSCIOUS, I TOOK IN A BREATH AND EVERYTHING WENT BACK TO NORMAL EXCEPT FOR HAVING A VERY BAD HEADACHE. A FEW MINUTES LATER, I WAS HAVING CONSTANT PALPITATIONS ( I HAVE ALWAYS HAD THESE BUT ONLY EVERY ONCE IN AWHILE). THE PALPITATIONS WOULD SUBSIDE AT TIMES BUT NEVER COMPLETELY STOPPED FOR ABOUT 24 HOURS. NOW, I FEEL VERY EXHAUSTED AND WILL HAVE A COUPLE PALPITATIONS HERE AND THERE. I JUST FOUND OUT THAT THE HEART STOPPING AND PASSING OUT IS WHAT MY OLDER SISTER GETS A LOT ALSO. DO YOU THINK THIS IS CAUSED BY STRESS OR POSSIBLY A GENETIC DISORDER?

### output:

Hello, I would like to tell you that palpitations followed by near fainting can be because of heart rhythm disorder which needs to be evaluated to avoid life-threatening events. Kindly get an ECG, Echocardiography, and Holder (ambulatory ECG) done and consult a cardiologist personally for further management. Heart rhythm disorder is generally not influenced genetically. Hope I have answered your query. Let me know if I can assist you further.
