[|Human|] For years, I periodically have some heart palpitations with tightness in the center of my chest. Heart test show not much going on, I just deal with them when I get them. Today however, I had a MRI for my lower back. I felt fine during the test but afterwards my chest ached. Similar to esophageal spasms, but I also had heart palpitations. My heart rate is about 120-134 bpm and I keep needing to deep sigh breathe every five minutes or so. I am 61 and was just sitting watching TV when I finally was concerned enough to check. I also have been hearing my heart pound below my ears on and off for the last month or so. I have a follow up with my Heart Dr. But not until Middle of July. Do I need to be concerned about this today?
[|AI|]  Hi Welcome to Chat Doctor. I understand your query and concern. Rapid heart rate and Dizzy spells can be a definite feature of heart rhythm disturbances. Irregular heartbeat is known to alter the blood supply to the brain leading to impaired function in a transient way. Few Chat Doctor. I advise you to have a complete 24 hour holder ECG which can accurately determine the cardiac conduction abnormalities. Monitor your blood pressure and heart rate.
