The rumors were sparked by a nationwide power outage and Musharraf's visit at a U.S. hospital. The president visited a cardiologist Saturday during a trip to Texas.
Musharraf was in the United States along with many world leaders to address the U.N. General Assembly. Thailand's former prime minister, Thaksin Shinawatra, was ousted in a military coup before his scheduled U.N. address.
