Coming from someone with a more intense version of your symptoms, I would just do it as needed. If your Dr said its non fatal then you have nothing to worry about. My heart rate is normal 140 beats a minute. I get these episodes every few mind that spikes my rate up to the 300s then it drops to the low 50s. You would think my heart rate is fatal, but in actuality, its not. Its just uncomfortable and stressful for me but my heart rate follows a pattern.. if that makes sense.
Hello. Thank you for your question.
In general, patient's with tachycardia due to sinus tachycardia (a normal fast rhythm with a heart rate greater than 100 beats per minute (bpm)) for a few hours is not considered dangerous. Patients with prolonged tachycardia could theoretically develop a cardiomyopathy, which is a decrease in the squeezing function of the heart. This often occurs for patients who are always or nearly always tachycardic (Heart rate (HR) > 100 bpm), not for patients who experience a few hours of tachycardia per day. This can be checked with an echocardiogram, which is a ultrasound of the heart.
I am not familiar with the practice of beta-blockers on demand for sinus tachycardia as this is not a dangerous arrhythmia. The much more common practice is for patients to be given a prescription for beta-blockers as a maintenance dose. However, the prescribing physician must make sure this does not drop a patient's heart rate or blood pressure too low, as this can cause worse symptoms than the tachycardia.
Lectopam is not a medication for arrhythmia, it is a medication given for anxiety. Decisions to use this medication are not based on heart rate, but your prescribing physician should base the decision on symptoms. I recommend you ask your physician if your symptoms of anxiety warrant this current medication.
I was on a daily dose of the beta blocker (Metoprolol) for near lifetime SVT. My GP doc said to carry a small supply, and chew an extra one when my SVT occurred (generally 4 to 5 times per month) as it MIGHT help. When I saw my cardiologist I mentioned this to him. His comment was (with a slight roll of the eyes) "It doesn't work that way". Nothing more. When it came time for my electrophysiology procedure, my electrophysiologist instructed me to discontinue the Metoprolol for three days prior to the procedure. I questioned the side effects. "There are no side effects or rebound effects from abruptly ceasing it" He told me that if my SVT occurred in that time, it was due to the missing Metoprolol that was formerly suppressing it.
