When the device was finally programmed, it forced both sides of Julian's heart to contract simultaneously. A Case-Based Approach to Pacemakers, ICDs, and ...

His heart walls were too thick, a genetic quirk that turned his greatest passion into a lethal gamble. Marcus didn't need a constant rhythm; he needed a "fail-safe."
