Any EKG should be thought of as a picture that directly represents electrical activity in the heart, which is causing physical or mechanical activity that can't be seen on the strip.
Sinus rhythms show up as P-waves, so this strip would have P-waves present. Normal P-waves face upward toward positive polarity. These sinus rhythms originate in the sinoatrial node (SA).
AV block means that the signal is not reaching the Atrioventricular node (AV). This shows up as an increase in the length & time between the P-wave and the R-wave.
The problem here is that due to something interfering with the electrical signal, the herat's ventricles are not pumping at the right time. This can be because of electrolyte imbalance (not enough or too much calcium, potassium and so forth), damaged heart muscle from myocardial infarction (heart attack), or due to medication side effects (especially heart medications like calcium channel blockers.

What are the different heart rhythms a paramedic would analyze?
Sinus Bradycardia Sinus Tachycardia Sinus Dysrhythmia Sinus Arrest Wondering Pacemaker Premature Atrial Complex Paroxysmal Supraventricular Tachycardia Atrial Flutter Atrial Fibrillation Premature Junctional Complex Junctional Escape Complexes or Rhythms Accelerated Junctional Rhythm Ventricular Escape Complexes or Rhythms Premature Ventricular Complex Ventricular Tachycardia (VT) Ventricular Fibrillation (VF) Asystole Artificial Pacemaker Rhythms First Degree AV Block Second Degree AV Block Type 1 (Wenckebach) Second Degree AV Block Type 2 Third Degree AV Block Disturbances of Ventricular Conduction Pulseless Electrical Activity (PEA) Preexcitation Syndrome: Wolff-Parkinson-White Syndrome Broad complex tachycardia Narrow complex tachycardia
What is a sinus rhythm and what other heart rhythms are there?
Sinus rhythm refers to a heart rhythm that is controlled by the depolarisation of the sinoatrial node. You can also have focal ectopic rhythms where random areas of the heart depolarise first and you can have supraventricular rhythms.
What causes first-degree heart block?
First-degree heart block or AV (arterioventricular) block, or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds.First-degree heart block rarely causes any symptoms or problems and normally remain undiagnozed.RegardsTime is imaginary
Id like to know what is to long to consider for a 1st degree block .22 to?
First degree atrio-ventricular node block is a PR segment longer than 0.2 seconds.
Which is the best antihypertensive drug for people with first degree AV block?
metoprolol succcinate 50/100 is the best for such cases BoB
The peaks and valleys of the electrical activity of the heart are?
The first little bump is the P wave it is followed by the QRS Complex that's the big spike and that is followed by the T wave which is a bigger bump than the P wave... normally that's only in a normal Sinus Rhythm
What will appear on ECG if a patient has pacemaker?
Depending on the reasons the pacemaker is being used in the first place. Patient may be having ectopic beats? irregular rhythms? due to heart conduction blocks or muscular damage. Expect a regular sinus rhythm with an occasional ectopic wave.
Who first introduced measured rhythm to music?
Although music has had rhythm since music was first conceived, the person who is generally held responsible for the invention of measured, fixed rhythm is Franco of Cologne.
What was enrique's first song?
Enriques first song was "Rhythm Devine"
What is the silent word in rhythm?
The first H is silent
What is the first block on the periodic table called?
The first block on the periodic table is called the S block.
If the no shock advised message is given during the first AED analysis you should?
Check for a pulse; if no pulse immediately resume CPR. The AED only shocks for 2 cases; V-Fib & V-Tach. If the problem with the sinus rhythm is not one of these two, the AED will not shock even though there is no pulse.
