I have unidentified chest pain . It is always upon waking. I recently had test performed that revealed a moderate, sharp diastolic murmur, felt also by placing hand on chest also. A sinus arrhythmia , as well as, non specificst- t wave abnormality. Dizziness from sitting to standing, collapsed twice, different from fainting . Almost like muscle weakness. The first time, my hands went numb. The test also revealed high creatinine, low Gfr. Past: numerous severe infections, e.g c-dif, numerous mrs a infections, chronic kidney infections. I was anorexic for years. What could the heart diagnosis be?
