I have gerd. i feel some quick spasms/pressure in chest that change my pulse. i'm checking it in the neck and i noticed that it jumps the beat.

See your doctor soon: You could very well have some cardiac issues occurring (like irregular heartbeat) which can and should be diagnosed soon. They can be very innocent, like atrial fibrillation, or they can be very serious and need medical intervention to prevent significant problems. See your physician soon to find out if your condition is innocent or if you need medical management for it.\.

GERD is probably: Not cause of cardiac arrhythmia. Some variation in heart rate with respirations is normal, but if you have many skipped beats, you should have a doctor listen to your heart. Most often, cardiac arrhythmia is not serious, but rarely it can lead to cardiac arrest. Have your doctor take a look, and listen.

Palpitations: Most likely this is nothing serious but you should check with your doctor. A monitor can help reconfirm the cause for this sensation
