One from a recent run. I don’t get to see this often. The alternating (relatively) normal QRS with a PVC is called bigeminy. Generally not good.
West Alex Fire was dispatched this evening for a report of a CO detector activation. Shortly after arrival, they requested EMS to evaluate the two residents. Apparently the CO meter went nuts as soon as the firefighter entered the residence. Both residents and the dog were fine. The problem was a malfunctioning gas water heater. The outcome could have been much worse!
