Thanks Jim. Problem is that it was congestive heart failure with an irregular heartbeat and my dad is in N. Cal in the middle of a 2 year contract at Diablo Cyn. Nuke plant (yes, he IS the original Homer Simpson!) She needs someone with her 24 hours a day until her heart is strong enough for a mini pacemaker or healed on its own. No problem with arteries; she just got sick (virus?) and it went undiagnosed for too long. All us siblings take turns with her. Sheesh she's only 63! She'll heal.
