Just to throw in my 5 cents. There's not a lot of difference between telemetry and med/surg, at least in the acute care hospital I worked for. Telemetry in fact is also med/surg with the addition of mostly heart patients (CHF, CADs, post open hearts[2nd, 3rd, 4th day post], pre, post interventional procedures [PTCAs, cardiac caths, pacemakers/AICDs, to name a few]). Of course, patients are all on cardiac monitors. So, in case you choose telemetry, you have to brush up on your EKG skills; care of patients with CHF, CADs, pre and post interventional cardiology, pre open heart, post open heart (not fresh open heart), patients with pacemakers/AICDs, and the like.
In the end, I will say go where your heart is, you're the only one who will know and feel it . Good luck.
