Valsalva Maneuver
This ancient technique can help restore a fast heartbeat to normal. It causes physical intervention that stimulates the 10th cranial nerve (vagus nerve). This in turn leads to slowing of the heart rate.

First, pinch your nose, close your mouth and then try to breathe out forcibly. This will accelerate your heart rate, and then slow down your heartbeat.

Deep Breathing
Deep breathing is one of the best ways to deal with heart palpitations. It helps ease anxiety as well as a panic attack and, in turn, helps normalize your heart rate. Deep breathing also helps relax the body and increase the oxygen supply to the brain.
Sit comfortably in a cross-legged position.
Take slow, deep breaths through your nose, allowing your belly to expand with each inhalation.
Breathe out slowly through your mouth.
Repeat for a few minutes until your heart rate slows down.
Cold Water
As a decrease in fluid intake can make the heart more prone to irregular heartbeats, try drinking a glass of cold water to help restore your normal heartbeat. It will also help reduce stress, anxiety and dizziness.
Splashing cold water on your face can also work well for palpitations and panic attacks. You can also take a cold shower. Cold water helps shock your nervous system to help get your heartbeat back to normal.
