I had a successful ablation for svt in May 2019 & a PM fitted in Sept 2019 for bradycardia . Over the past few weeks I have noticed my heart attempts to go into svt again, all the old warning signs are there but so far the symptoms have lasted at most 20 seconds or so without going into a full blown svt. Has anyone else experienced this. I'm getting a tad breathless with little exertion at times.es as well. A tad awkward to approach pacing team & GP in the current climate crisis. Any feedback will be gratefully received thanks.
