I have been palpitations and rapid heart beat recently so been for blood test and ECG today. The nurse who did the ECG didn't make any comment if the test was ok but made a lot of umm noises and then said you must make an appointment to see the GP next week. Now convinced that there is something really wrong. Can practice nurses read ECG results? If there was something really wrong would they be raising it with GP before next week or would they have called a doctor before letting me go?
