Sinus Node Dysfunction • A common clinical syndrome, comprising a wide range of electrophysiologic abnormalities from failure of impulse generation, failure of impulse transmission to the atria, inadequate subsidiary pacemaker activity, and increased susceptibility to atrial tachyarrhythmias • Variably termed the sick sinus syndrome, tachycardia-bradycardia syndrome, SA disease and SA dysfunction

Take home points • YOU DON’T NEED TO BE A CARDIOLOGIST TO READ THE ECGS • It can be done by anyone! • The Best Person to read ECG are NOT one specialty to one another, but person who has a lot of PRACTICE! • Just because of ECG is a basic skills in ED, doesn’t mean that our skill should be BASIC, you must be expert in ECG ….
