Heartbeat (9 p.m., NBC) – If you’ve been thinking the world needs another medical drama, you’re crazy – but you’re not alone. NBC’s newest is based on Dr. Kathy Magliato’s book “Heart Matters: A Memoir of a Female Heart Surgeon,” and stars Melissa George as the unconventional heart transplant surgeon. The pilot episode is straight from Magliato’s life, recalling an instance when she had to save someone’s life on a plane. It’s not the usual dour, super intense offering (like, say, “Code Black” or “Chicago Med”). It veers to the dark side now and again, but only briefly; overall, it has a pretty upbeat and often funny quality. And the cast is solid: Dave Annable, Don Hany, Jamie Kennedy and D.L. Hughley. I didn’t expect to, but I liked it. It moves to its normal timeslot tomorrow (Wednesday) at 8.
