Without a magnifying glass, I believe I might be seeing a "P" wave on the "T" wave in V1. With that being said, one could guess a AVNRT but one can always be safe and say a "regular SVT" with a ventricular rate around 188 BPM.
Supraventricular tachycardia, but there is also a slight ST depression in V3 probably caused by ischemia of septum or front heart wall.
this is junctional tachycardia , in some leads slight slurring upstroke of r wave is visible suggestive of AVNRT
