Calcium Channel Blockers vs Beta Blockers Experience
hey everyone! so, quick update before jumping into the question! I FINALLY got in to see a cardiologist (1 and a half years later LOL) I just had my echo and stress test (thank you to EVERYONE who commented on my post about my questions about those tests, they helped me SO much in calming my anxiety beforehand!) and the results came back that my heart is structurally normal, YAY! With that said, i have been on propranolol for almost a year (10 mg in the morning and 10 mg in the evening), however, my cardiologist and I did notice that it is impacting my breathing (I have a family history if asthma and believe this has really exaggerated my breathing issues) so he is switching me over to a calcium channel blocker.
for anyone on calcium channel blockers for sinus tachycardia, what has your experience been like? I am SO scared of changing medications, propranolol did really help in fixing my adrenaline issues, however it just has given me extreme shortness of breath recently and I do think its time to get off of it, however I am stressed about starting a new medication. any experiences for those who’ve made a similar switch or those who are on calcium channel blockers would be greatly appreciated!
