How CRT Strengthens the Heart Muscle Revealed

The method through which a modified pacemaker, fitted through a process known as cardiac resynchronization therapy (CRT), is able to strengthen the heart muscle and make it beat in a coordinated fashion has been discovered by researchers at Johns Hopkins. In a new study conducted on animal heart cells described in the iJournal of Clinical Investigation/i, the scientists show that CRT changes these cells so they can contract more forcefully. The researchers also ...
