After the onset of palpitations, the patient can perform slow rhythmic breathing to relieve panic and palpitations.
Inhale gently and exhale slowly, one round trip lasting six seconds, making sure to do it slowly. Repeat this about seven to eight times and then change the slow breathing to deep breathing to relieve the symptoms of palpitations and panic.
