CardioNet Inc., a Conshohocken heart monitoring company, is getting its third CEO in three years.

On Tuesday, the company named Joseph H. Capper president and chief executive officer, effective immediately.

He succeeds Randy H. Thurman, who'd been president and CEO since February 2009. Thurman will remain chairman of the board.

Capper had been president and CEO of Fort Lauderdale, Fla.-based Home Diagnostics Inc., which was acquired by Japan's Nipro Corp. earlier this year.

Founded in 1999, CardioNet has developed a digital monitoring technology for patients with heart rhythm disorders. But it sustained a setback last year when insurers cut their reimbursement rates for the service. CardioNet lost $20.5 million, or 86 cents per share, on revenues of $140.6 million in 2009.

According to CardioNet's most recent proxy statement, Thurman received a salary of $442,308 and a bonus of $375,000 in 2009. He also received stock options and stock awards that pushed his total compensation to$10.46 million last year.

Thurman had succeeded Ari Cohen as CardioNet CEO. Cohen had received a salary of $450,000 in 2008.

No word yet on the compensation package for Capper.
