sinus rhythm regular rhythm Set by SA node at 60 to 100 bpm P waves normal normal qrs PR 0.12 - 0.2 normal qrs less than 0.10 wide qrs is greater than 0.12 Sinus Tachycardia 100-160 bpm SA node reduced time for ventricle filling assess for SOB or chest pain a prolonged QT interval more prone to arrhythmia NSR reflects the heart's normal electrical activity, providing synchrony between the atria and the ventricles. Sinus tachycardia occurs when the sinus no...

Third Degree Heart Block correct answer: Occurs when atrial impulses are completely blocked at the AV node and fail to reach the ventricle; atria and ventricles are controlled by different and independent pacemakers Third Degree Heart Block Causes correct answer: inferior or anteroseptal MI Third Degree Heart Block Clinical Manifestations correct answer: dizziness, syncope, fatigue, exercise intolerance, HF Third Degree Heart Block ECG Rate correct answer: atrial 60-100 bpm; ventric...

Sinus node initiates regular impulse at a slow rate. Ea. Impulse is conducted normally to the ventricles correct answers Sinus Bradycardia Sinus node imitates regular impulses at a fast rate. Each impulse is conducted normally to the ventricles correct answers Sinus Tachycardia Sinus node fail to initiate an impulse in an expected time ~ Depression of SA node automaticity Often no treatment needed - episodic correct answers Sinus Arrest Different between sinus arrest vs sinus pause c...
