A heart rate of 45 bpm and an absence of P waves from the ECG would suggest?

A heart rate of 45 is probably bradycardia. Generally anything less than 60bpm is considered bradycardia (slow heart rate).
The P-wave is more complicated. To me this sounds like an electrical problem.
The P wave originates near the SA node after it produces electrical stimulation of the right atrium as it travels toward the AV node. This is recorded as the P-wave if the EKG equipment can sense it. If there is some disturbance of this electrical impulse or it is abnormal, that might be a possible cause of an absent P-wave.
An absence of P-waves with QRS totally present could mean that the rhythm started somewhere in the AV junction (Barbara Aelert, p.76) instead of where it was supposed to start.
Usually P waves are either positive (upward) or negative (downward). The most obvious explanation for a totally ABSENT p-wave would be that the lead (II) is disconnected! That would be the first thing to check... that would be nice because it would mean that you just made a mistake with the EKG and the person's heart might be fine.

Does smoking fasten the heart?
yes it suffocates the lungs and the heart making it difficult to breath and pump blood i would not suggest smoking as a hobby or a habit
How would the heart be affected if the purkyne tissue ceased to work?
The waves of excitation would not be carried to the bottom of the heart first and it would spread over the ventricular walls from top to bottom causing the ventricualr muscle to contract in a way that it pushs the blood downwards. The blood would however end up going through the arteries because of the immense pressure but less will be pumped through the arteies with every contraction hence leading to less blood being pumped in the heart
What would happen if water waves were Compressional?
They would likely have much less of an impact than real ocean waves do. As it is, the only compressional waves that can move through water are sound waves, as water is, of the most part, incompressible, as are most liquids and solids.
Why is your heart an involuntary?
Your heart is involuntary because you cannot contract your cardiac muscle or" heart muscles". it would be terrible if your heart was voluntary. You would have to remember to pump your own blood or you would die :)
High heart rate mean heart problems?
An abnormally high pulse is referred to medically as tachycardia. This is where the pulse rate is greater than or equal to 120 beats per minute while at rest.It means that the heart is pumping blood very quickly. This often happens after intense exercise or a fearful experience. It is good to rest if this occurs to bring the pulse rate back to normal.
Where do we find waves or ripples?
As the category is not stipulated: I would suggest waves and ripples can be found at the sea side.
How long will dark reactions run in the absence of light?
I would go with dark being the absence of light, since light is actually something (electromagnetic waves).
Would you be deaf on the moon?
In the absence of a medium to transmit sound waves, there would be no sound to hear. This is not the same as clinical deafness, which would be the physical inability to hear or process sounds.
How would exercise affect heart rate in the absence of any innervation?
Since these is no nerve supply, the heart would keep a normal rate. It would not be able to keep up with the demand for oxygen and nutrients. A heart without a nerve supply would not be viable.
What do you do when somebody very close to your heart left you...?
You have to move on. You may, of course, keep that person close to your heart, but you can't lament on his/her absence forever. The person would probably wish that for you.
What are some good vitamins for the heart?
I suggest you taking B vitamins. B vitamins can help your heart grow, and become stronger. I would suggest talking to your doctor on vitamins that would help you specifically, without disrupting anything in your body.

What is it called when there are no QRS waves following p waves?
The QRS complex and the P wave are features of the electrocardiogram, which graphically displays the electrical activity of the heart. The P wave is generated when the atria, or upper chambers of the heart contract. The QRS complex is generated when the ventricles or lower chambers of the heart contract. If there is a P wave but no QRS, the the heart's main pump is not functioning. This would cause death quickly.
The absence or inhibition of AChE at a synapse would lead to?
The absence or inhibition of AChE at a synapse would lead to flaccid paralysis.
How do you know if a guy is done with the relationship?
His absence from your life would be a good clue. Also his dating someone else would suggest he's moved on and that it's time, also, for you to move on.
What advantages would a telescope in space have over a telescope on earth?
The main advantage would be the absence of an atmosphere. Any telescope on earth can only "see" electromagnetic (light) waves after they have travelled through the atmosphere, losing some of their directional integrity, which distorts the image seen in earth bound telescopes. Some light waves never make it to the telescope at all.
Is it bad that your heart beats on average at 109 per minute?
if that's your resting heart rate, then it's bad. If it's a working heart rate it's probably OK
