Cardiologist Aurelio Rojas shares three simple tricks to calm palpitations

Cardiologist Aurelio Rojas outlined three simple techniques to ease palpitations and tachycardia. The first involves inhaling for four seconds, holding the breath for four seconds, then exhaling slowly for six seconds to calm the nervous system and regularize heart rate.

If that fails, he suggests a forceful cough, and as a last resort, immersing the face in cold water for ten to twenty seconds.
