Wirtham is a physician and surgeon, and the owner and administrator of a biological research firm. Elias Wirtham is driven by his brother's death to research life-saving medical practices. His brother Joshua's death was the result of corporate greed. A corporation had a cure for his condition ready, but did not distribute the medicine due to it not being a "profitable" time for them, hence Cardiac's motivation against corporations. As a part of his research, Elias replaces his heart with a beta-particle reactor, which supplies energy throughout vibranium weave mesh under his skin. This energy, channeled through his muscles, increases his speed, agility, and reflexes, and can also be fired through his fists or the power staff he wields. He adopts the moniker "Cardiac" in reference to the source of his power.''The Amazing Spider-Man'' #376 (April 1993)Fighting resumes
Cardiac becomes a vigilante, believing himself an instrument of justice.

Cardiac subsequently battles Code: Blue. He returns periodically to perform his version of justice. He will kill criminals, but he is often bothered by his conscience as a result. When he targets a shipment of drugs, Cardiac again encounters Spider-Man, defeating the hero. Cardiac destroys the shipment, saying that he wasn't "there to destroy a misguided hero". Cardiac helps Nightwatch (comics), NightWatch to take down the corrupt corporation which gave him his powers. Cardiac also confronts Ghost Rider (Johnny Blaze), Johnny Blaze and Ghost Rider (Daniel Ketch), Ghost Rider during Blaze's mission to rescue his missing son from an evil corporation.

Elias was listed as a "potential recruit" for the Avengers: The Initiative, Initiative program, according to ''Civil War: Battle Damage Report''.Fear Itself
During the ''Fear Itself (comics), Fear Itself'' storyline, Cardiac deals with the fear and chaos in his area when he comes across Charles Davies, CEO of Jerixo Healthcare, and tries to help his son who has meningitis.Working with Superior Spider-Man
As Dr. Elias Wirtham, he opens the new Hospital for Emergency Aid and Recuperative Therapy (H.E.A.R.T.) in the former site of Mister Negative's homeless shelter. As Cardiac he has stolen items to help aid patients being treated there. On a trip to "procure" a device to help a girl with severe brain damage from "The Boneyard" (a police impound for confiscated supervillain items), he fights with the The Superior Spider-Man, Superior Spider-Man (Doctor Octopus' mind in Peter Parker's body). Due to Peter's interference with Doctor Octopus, Cardiac is able to temporarily stun Spider-Man with a strong blast and escape with the Neurolitic Scanner (a device that Doctor Octopus had invented to develop his mind link to his tentacles), but not without being tagged by an old spider-tracer.''The Superior Spider-Man'' #7 (April 2013) Wirtham is preparing the Neurolitic Scanner that he previously stole to scan the brain of his patient Amy Chen to find a damaged area of her brain. It becomes difficult due to the complexity of the device. Cardiac replies that the only one who can handle it properly is Otto Octavius. When Wirtham is preparing for his surgery, the alarms at H.E.A.R.T. Clinic activate. As Wirtham changes into Cardiac, he notices a Spider-Man#Powers, skills, and equipment, Spider-Tracer as Otto arrives. Otto demands that Cardiac surrenders the Neurolitic Scanner, and Cardiac refuses. They battle in the hospital. While Otto tries to fend off the attacks, Cardiac tries to delay him but fails. Otto finds the Neurolitic Scanner on Amy's head and even tries to retrieve it, but Peter refuses to allow him to do so until Cardiac manages to stop him. Otto demands an explanation, and Cardiac reveals that when Otto tried to kill the planet with his Heat Satellites, he didn't considered about those who were already sick like Amy (whose parents died in an accident caused by his scheme), and she barely survived with severe brain damage. Otto feels remorse for this and decides to help Cardiac with the surgery, offering to perform the surgery himself. Even though Otto is having minor afflictions with his hand, the surgery is a success. Cardiac thanks Spider-Man for the help, and Otto replies that he was wrong about him and offers his help on anything which makes Cardiac allow Otto to borrow the Neurolitic Scanner. Dr. Wirtham oversees the operation of Aunt May's leg and tells her that her leg is now fully healed upon completion of the surgery. When Otto has plans to make artificial legs for Flash Thompson with him being the first subject for this operation, Wirtham worries about some last-minute add-ins to the procedure. When the Superior Spider-Man gets the Venom (Marvel Comics character), Venom Symbiote (comics), symbiote on him and gets it under his control, he knocks Cardiac aside. When the Goblin Underground is attacking Manhattan, Cardiac is seen fighting the Norman Osborn, Goblin King's minions. While Cardiac was away fighting the Goblin King's minions, the Goblin King has the H.E.A.R.T. Clinic destroyed.''The Superior Spider-Man'' #29Powers and abilities
Cardiac's heart has been surgically replaced with a compact beta-particle reactor, which grants Cardiac power. He has the ability to channel beta particles through the neural web of his vibranium-mesh skin into his muscles thereby endowing him with superhuman strength and regeneration, and enhanced speed, agility, reflexes and endurance, and he can channel these particles through external objects (such as his pulse staff and hang glider). He wields his pulse staff which fires concussive force bolts in a distinctive pulse-like energy signature, and rides a beta-propelled stingray hang-glider, which were both invented by Wirtham and his associates. His vibranium-mesh skin is also able to stop a couple bullet shots before the beta-particle energy is depleted. Dr. Elias Wirtham's business administrative skills provide him a strong power base with a number of connections to various enterprises. He has also earned an M.D. degree and is an accomplished physician and surgeon.References
