Etiology of Sinus Brady (causes) - ANSWER-• Lower metabolic
needs - Sleep,
Athletes,
Hypothyroidism
• Vagal stimulation (triggers parasympathetic) - Vomiting,
Suctioning, Pain
• Medications - CCB, BB,
Amiodarone
• Idiopathic sinus node
dysfunction
• Increased intracranial
pressure
• Coronary artery
disease
*Management will depend on cause and
symptoms
,H's and T's for abnormal heart rhythms (6/5) - ANSWER-•
Hypovolemia - weight loss, low BP, incr. HR, concentrated
blood (high hematocrit), turgor/tenting
• Hypoxia - cyanosis (mouth, periphery, O2 sat below 95-100)
• Hydrogen ion (Acidosis) - more hydrogen ions, ABG (low pH,
bicarb ≤22, low CO2 = compensation, CO2 will be high if the
cause bicarb above 26)
• Hypo/hyperkalemia - weakness, change in T waves
• Hypoglycemia - cold and clammy give candy
• Hypothermia
• Toxins - meds, comorbidities, kidneys (main excreters - will
see high BUN, Cr, decr. urine and GFR)
• Tamponade, cardiac - fluid buildup around heart
• Tension pneumothorax - collapsed lung r/t air; will present
with absent breath
sounds on affect side, low O2 sat, tracheal
shift, SOB
• Thrombosis - chest pain, neuro
changes, etc.
•
Trauma
Sinus Tachycardia - ANSWER-• Atrial/ventricular rate and
rhythm: > 100, but <
, 120 and
regular
• P wave: Normal and consistent shape; always in
front of QRS
• PR interval: Consistently between 0.12 and
0.2 seconds
• QRS shape and duration: Usually normal, but may be
regularly abnormal
Idioventricular Rhythm - ANSWER-• Atrial/ventricular rate and
rhythm: Ventricular rate between 20-40; if exceeds 40 known as
accelerated idioventricular rhythm; regular rhythm
• P wave: None
• PR interval: Cannot measure
• QRS shape and duration: Bizarre, abnormal shape; duration
0.12 seconds or more (widened)
• neither SA or AV are working; purkinje fibers take over (20-
40bpm, compromised output)
Aystole - ANSWER-• Atrial/ventricular rate and
rhythm: No heartbeat
• P wave: May be apparent for
short duration
