Vilka material kan en kateter vara gjord av?
Det finns katetrar av latex och av silikon. De har olika egenskaper, och du kan diskutera med din vårdgivare vad som passar just dig bäst. Latex är ett mjukt och följsamt material, men ren latex irriterar vävnad och har därför en beläggning av silikon, teflon (PTFE) eller hydrogel.
How are PVCs diagnosed in patients with PVCs?
Clinical Approach to Patients with Frequent PVCs. In addition, the 12-lead EKG can be used to assess whether PVCs are monomorphic/monotopic (suggesting a single site of arrhythmia origin) and whether one should look for possible structural heart disease (i.e. LVH, Q-waves in patients with prior myocardial infarction).
What does it mean if you have PV’s that come and go?
Response to exercise: PVCs that mostly occur at times of rest and suppress with exercise are usually benign. PVCs that worsen with exercise may be indicative of a heart under stress, say from a partial blockage of an artery or something else.

Urinvägar. Urinvägarna består av njurar, njurbäcken, urinledare, urinblåsa och urinrör. Njurarna har två huvuduppgifter, att avlägsna slaggprodukter ur blodet samt reglera salt- och vattenbalansen i kroppen. Det som inte går tillbaka till blodet utsöndrar njurarna i form av urin.
