Hi @sistertwo. I'm always partial toward a second opinion, but it's important to be specific about the question you need answered. Are you and your significant other concerned about the Cpap the VA wants him to use? If so, the VA needs to be pressed on whether they have an alternative mask they can provide. It's possible they don't, so a second opinion would be necessary. If your main concern is also about his heart rate doubling from time during the day, is your medical advice now coming from a cardiologist or an electrophysiologist? If it's one OR the other, I'd think about consulting the other for the first time -- for example, talk to the cardiologist about what the electrophysiologist has said and is recommending. Also take into consideration his other symptoms related to those times when his heart rate speeds up while at rest. Questions about that also need to be explored with your regular doctor as well as the other doctor giving you a first opinion or a new doctor providing a second opinion. Either way, be prepared when visiting another doctor to press for a full workup of his medical history and current symptoms so you are satisfied that the doctor has the full picture in view. Martin
