The rule of thumb for pediatric cardiology is that diastolic murmurs are always abnormal but systolic murmurs can be benign or a sign of a structural abnormality.
Your grandson has a systolic murmur. Pediatric cardiologists estimate that benign murmurs can be heard in nearly 90% of children. Without a clinical exam and ultrasound imaging, it is impossible to determine if your grandson’s murmur is benign or suspicious but it is wise to have him further evaluated.
The next step in your grandson’s workup is a referral to a pediatric cardiologist, an electrocardiogram (EKG), and/or imaging of the heart with an ultrasound machine. With those pieces of information, your child’s pediatrician can make an informed decision for your grandson’s care.
With regards to the wait for the appointment, it all depends on who your grandson was referred to and when his/her next office appointment would be. It doesn’t hurt to call the physician’s office to ask.
