On a cold and cozy December night in 2018, Jim Kaveney thinks he is dying. He is a husband, a father, a business owner, an athlete, and innovator. He is also an Afib patient facing massive cardiac trauma.

In this breakout memoir, Jim Kaveney recounts his dance with death and the events of his life leading up to this fateful, health-defining moment and the shifts in business perspective and priorities that followed.

Unlimited Heart takes readers on a three-part, forty-year journey. It traverses the tight budgets of an eleven-member household to the financial burdens strapped to a dream to the sale of a multi-million-dollar startup. It is a raw portrayal of a boy who grapples with his own demons in the midst of his dreams and a man who turns those dreams into a clear, entrepreneurial vision--a vision that is threatened by medicine, technology, and surgeries.

Kaveney's entrepreneurial and cardiac journey cannot be separated. Where his heart was weak, his mind became strong. When his mind was weak, his heart was strong. His battle between his metaphorical and physical heart and mind is what inspired him to write Unlimited Heart and to launch a business with the namesake. Turning his pain in life to a greater purpose, Unlimited Heart helps people with cardiac issues be different and better patients.
