Afib Telemetry Strip. Atrial fibrillation or a fib can lead to fatal heart complications if it reaches a severe enough stage. Qrs complexes usually 120 ms unless pre existing bundle branch block accessory pathway or rate related aberrant conduction. The p wave will be positive but its shape can be different than a normal sinus rhythm because the electrical impulse follows a different path to the av atrioventricular node. With a fib you may see small irregular flutter waves kind of like a bumpy road which can sort of resemble p waves.
A characteristic sign of a fib is the absence of a p wave in the ekg signal. The normal duration interval of the qrs complex is between 0 08 and 0 10 seconds. The next large upward spike segment the qrs complex is formed when the ventricles the two lower chambers of the heart are contracting to pump out blood. Shown below is a strip from a patient being cardioverted for atrial fibrillation. When interpreting a fib on an ekg strip the rhythm will be irregular and not have p waves. Symptoms of atrial fibrillation can include shortness of breath exercise intolerance heart palpitations and weakness.
