Esophageal Spasms Or Heart Palpitations? in Sclero Forums (MAIN) Posted February 9, 2007 Hi Barefut,It's my understanding (and please correct me if I'm wrong!) that if it is a mild and fleeting thing, it may be nothing to worry about. If it is stronger or recurring, you will need to check with your doctor on it.Many people have palpitations without any underlying heart disease. Major culprits for that are coffee and stress. See our section: Arrhythmias, Palpitations, and Conduction Disturbances.Spasms in the esophagus (throat) can also give some interesting feelings, as can any fasciculations (tiny muscle spasms or tics or twitches). Fasciculations are usually harmless and often caused by things such as caffeine, stress, magnesium deficiency or even withdrawal from some medications.You may want to read up on palpitations and such, and of course, consult your doctor over any new or worsening symptoms (because I'm not a doctor, I have no medical training at all, and I could be wrong, I often am!).
