What is the difference between a heart murmur, tachycardia and a cardiac arrythmia?

Common problems. A heart murmur is blood flow that can be heard with a stethoscope. This can be normal flow or abnormal flow. Tachycardia is the finding of a heart rate above the normal resting heart rate for your age. Arrhythmia is defined as the electricity moving through the heart in an abnormal pattern. There are many types of arrhythmia, some benign and some serious.
See below. A heart murmur is an extra sound. It can be significant and require medical intervention, or it can be just a noise. Tachycardia means the heart is beating fast. Arrhythmia means an irregular pattern of heart beats. All three can be harmless or bad, depending on the circumstances in which they are found.
