Hi Heart palpitations after eating can be caused when the heart begins to pump blood back to the stomach to help the digestion process. This activity can sometimes be felt by some people as an abnormal heartbeat. Other causes include fluctuations of blood glucose and its effect on the heart, overeating, and eating spicy foods. In addition, drinking caffeinated beverages such as iced tea and coffee with meals may cause heart palpitations. When other symptoms accompany an abnormal heartbeat after eating, such as chest pain, dizziness, sweating or shortness of breath, further evaluation by a medical professional is recommended. In addition, people who suffer from gastroesophagel reflux (GERD) sometimes experience palpitations, chest pain, and pressure after eating, which can even mimic the symptoms of a heart attack. Eating too quickly and swallowing air can cause pressure in the chest, leading to changes in the heartbeat. While this sensation can provoke anxiety, it is rarely serious. The drug betaloc is a betablocker and it slows heart rate. Hope this answers your query
