I have just had a big weekend in hospital for treatment of my second bout of AF. First one was 2 years ago and had cardioversion. I have had funny beats now and then but no AF until Saturday night. My cardiologist had advised me to present to A and E for pill in pocket trial when I next got AF so that was the plan.
The Registrar contacted my Dr and the covering cardiologist for the practice advised 100 mg Flecainide and 12.5 Metoprolol. Then my Cardiologist rang back and said 300mg Flecainide and 25mg Metoprolol. After about 2 hours I suddenly felt very weak and dizzy and the cardiac monitor alarmed. I had an 8 second asystolie with no heart beat. Then my heart started beating and I was back in sinus rhythm. It felt like a generator had kicked in but my Hr was quite slow and BO low. As this was my firs5 trial of Flecainide I was admitted to CCU for overnight monitoring. When I got up to the ward! About 1/2 hr later I started to feel dizzy and weak but this time it was worse. I felt like I was slipping away. A met call was made and I was given atropine and adrenaline Intravenously as my HR was between 12 and 20 beats per min and my BP was 60/ 0 , as you can imagine I was slipping away. Thankfully those drugs brought me round and I was still in sinus rhythm. It was extremely frightening. I think the dose was too strong for me. I weigh 68kg, am 171 cm tall and am 61. Any advice or feedback or if anyone has had a similar experience? Thanks Christine.
