In people who have good heart rate variability—that is, whose hearts beat with a wide range of speed and intensity—are at far lower risk than people whose HRV is more restricted. Heart palpitations may feel like your heart is beating too quickly, beating irregularly, fluttering in a strange way, or thumping hard in your chest, according to the Mayo Clinic. Because death is very complex thing. A heart palpitation is the sensation that your heart has skipped a beat or added an extra beat.
